Those "bad generalizations" are taken directly from the original designers goals. They succeeded quite well. Even the antecedent cartridges were tilted in the same direction: The .30 Remington was designed for a self loading deer rifle competing against the .30-30 Lever action. And the 6mm PPC was the origin of the 6.5Grendel, a long distance precision target round.
The generalizations are quite accurate, what some cry foul about is not trying to use the cartridges in "off label" applications. You can, just expect you're not applying them in their window of optimum performance. They will be compromised and not function to the same degree.
Case in point, the 16" or shorter use of 6.5Grendel. Carbine applications are for short range use - not 600 to 1000m targets. Since the high BC bullets don't travel as far in the typical 350m shooting that carbines do, they don't travel far enough to "save" the energy and have it down range. It's a mistaken notion to think they deliver more energy at close range - they don't have it. They simply lose less at longer ranges.
What you wind up with is a compromised design that runs middle of the pack, not the ballistics trumpeted by fanboys as "superior" to the .308. That cartridge would do as well in a 16" barrel, if not better. The disadvantage is that it would still be 1.5 pounds heavier and have some serious muzzle blast.
There's another generalization - short .308s are heavy and noisy. While anyone can nitpick a generalization, they exist for a point - to communicate information in a shorthand way about something.
A generalization is usually considered "bad" because someone can't abide that it says something they dislike. Not necessarily that it doesn't apply.
