You are right for the most part, the exception being the 152s saw quite a bit of use in those last days of the war, claiming a number of enemy fighters in combat, both Eastern and Western in origin.
From my perspective, we already had the 152. We're not arguing/debating it's new addition.
I think that IF it were absent from the game and folks were debating it now, I'd be less for it than, say, a Me410 or a Ju188 (or heck, a Ju388!!) or the He162 or any number of other planes.
Since we have it, I'm fine with it. It's done with, I'll enjoy it.
If it were a fresh debate, that's another matter.
