Geez...Peet...you've been on this forum for years and you know that there are zillions of guys with guns that don't do anything better than something else. I don't have a 204, but a guy I know has 7 of em. He's happy. I know a guy with a 30-40 Krag and a 32 Winchester. Why would he want those two? Heck if I know. And I just met a guy at a gunshop with a 17 Bee Ackley Improved. I guess he's going grasshopper hunting, but he loves that gun (custom single shot job). Gotta admit, the thought crossed my mind to get one. Cool caliber. I'm the guy that's been trashing 223's for years, and now I have one. Go get one. Quit fighting it...join us here on the dark side
The true dark side is where people shoot cartridges that make the majority of shooters cringe.
".30-40 Krag, why would you want that?"
".22 Hornet? That's a stupid remnant from the days of crappy .22 caliber bullets."
"You hunt squirrels with a .416 Rigby? ...."
".220 Swift? I didn't know those were still around."
".500 Overbore.... What kind of a cartridge is that?"
".32 S&W? I have a BB gun that's more powerful..."
".240 Weatherby? That ammo is almost $100 a box!"
Some people don't enjoy owning and shooting the flavor of the month. Some people don't buy firearms just for the cheap trigger time factor.
Some of us see the true identity of the so-called "obsolete", "useless", and "stupid" cartridges.
The only common chamberings I own are 9x19mm, 7.62x39mm, .243 Win, .270 Win, and .30-06. Everything else is an "oddball", "obsolete", or offbeat.
Everything I own was purchased for a very specific reason, though. Each firearm has a very specific job to do, and they do it better than common chamberings. If they can be 'stretched' to do additional duty, that's a bonus.
Which brings me back to the OP:
I'm with Peetzakilla - In this particular case, the .223 is a superfluous addition to the lineup (for practicality). The .243 will do everything the .223 can. The .204 will do more than the .223 can, for varmints. --With one exception: .223 ammo is cheaper than either of the other cartridges. If super-happy-fun-time includes excessively blasting away at random targets and requires large amounts of ammunition, the .223 should stick around.
Side note:

You're dramatically under estimating the capabilities of the .17 Bee (and its improved version).
I hunt Elk with a .30-40 Krag. I bought the rifle specifically for that purpose. .30-30 doesn't have the power. .30-06 has too much. .30-40 Krag launches 180-200 gr projectiles at
exactly the velocity I wanted, and came in a sweet 115 year old rifle.
