An RMR with a battery is 1.2 oz. I get that ounces = pounds, but the weight argument isn’t one that’s overly relevant, imo. I do agree they add bulk, and depending on how and where on your body you carry that may be a problem. I don’t personally find it problematic, but I understand some may.
How significant 1.2 oz is depends on how much you value weight and how heavy the pistol is to begin with. My two lightest handguns weigh less than 10 oz unloaded so the RMR you mentioned would increase their weight by 12% or more. That being said, the added bulk is more my concern as when I carry a small handgun, it's usually in a pocket holster and when I carry OWB (I've never found IWB to be particularly comfortable) its usually with a large enough gun that extra bulk would be problematic. The extra bulk of the red dot also limits my choice of holsters somewhat and some of my favorite holsters are not available for guns with a red dot.

A red dot equipped pistol can make POA hits at 7 yd up to 50 yd as well as in between those distances and beyond. Will the POI vary slightly based on the range to target? Yes, as is true of iron sights. If your main aim is defensive style shooting I can fairly confidently say the POI offset at the distances you described is not enough to turn a “good” hit into a “bad” hit at those distances, absent a very specific “corner case”.
I'm not so confident in that. The handguns that I shoot out to 50 yards are chambered cartridges that are relatively high-velocity, and thus flat shooting, at least by handgun standards like .357 Magnum, .44 Magnum, and 10mm Auto. With iron sights, I notice a significant difference in POI between shorter and longer distances and the higher sight offset of a red dot could only accentuate this. Is the difference insurmountable? Probably not but I don't want to make things any more complicated than I need to.

I think there is a misunderstanding when it comes to the learning curve associated with red dots. Learning to use a red dot does not mean that if you go back to using iron sights that you will need to completely readjust how you are using the pistol. I and others I have talked to have found their iron sight shooting has improved after learning to use a red dot. Often this is a function of needing to have a better, more repeatable presentation with a red dot equipped pistol in order to see the dot readily. I shoot red dot equipped pistols every week. Last month I did a half day of shooting with my S&W Model 19 without a red dot. I shot it better than I ever have and that was even after months of not shooting it. Having one or many red dot equipped pistol(s) will not ruin your skill with pistols without red dots, in my experience.
I don't think that the difference is insurmountable or that using a red dot will "ruin" your iron sight shooting, but its another complication that I, personally, would rather not add. I own a variety of different pistols with differing styles of controls, actions, triggers, etc. and, because of this, I try to use techniques that are as "universal" as possible. For example, because not all of my handguns have a slide stop that is easy, or even possible, to use to release the slide, I've adopted the "slingshot" method for reloading because it works with all of my semi-autos. I also use a "thumbs down" grip and press the trigger with the distal joint of my finder because those techniques work well for me with both revolvers and semi-autos.
You also mentioned that you shoot red dot equipped pistols weekly. While I commend you for your diligence, I don't get the opportunity to shoot nearly that often due to time, finances, distance, and life in general. Because I can't get nearly the range time in that you do, it would likely take me a lot longer to develop proficiency with a red dot. I've been shooting handguns with irons for decades and, while I may be rusty and thus not as proficient as I'd like, the basic skill is still there if somewhat atrophied. Likewise, many of my handguns are not only for my use, but for other members of my household who, unfortunately, get to the range even less frequently than I do. For these people, developing proficiency with a red dot is a skill that may never come and thus having one on a pistol that they have to use would be more hindrance than help.
Finally, as I said earlier, the majority of my handguns simply aren't practical to put a red dot on. In actuality, I only own one pistol that is cut for a red dot: my S&W M&P 2.0 10mm. Many of my handguns are older and out-of-production and modifying them to accept a red dot would significantly diminish their value and still others simply aren't capable of being so-modified (I think an RMR might actually be just a big, if not bigger, than my Beretta Jetfire or Kel-Tec P3AT
). Even of the ones which I might be willing to have milled, the expense of doing so doesn't offer enough benefit to be worth it to me. I'm not trying to say that red dots aren't worthwhile for anyone, just not for me.
