While that is very radical, I may have to agree...Maybe we can have a cut-off date for planes? And besides, the whole idea is that even older planes can be modified to make them not only up to date but also make them multirole, so the MiG-29 isn't the only multirole that is possible. Even the A-4 can be made multirole, like Brazil has done with theirs, making them fourth-generation fighters comparable to the F-16 (I can scan the article about this from Combat Aviation Monthly if anyone wants).

I had originally made the decision that the majority of the aircraft would be from before 1980, and I'd rule out anything that has too many 'modernised' variants, or that was too common, which was why the F-16 etc. didn't make it in in the first place. 
I agree with you entirely about the A-4, and the only reason I didn't select one was because I have a character who uses one in another RP.
As it is, I feel pressured into adding the other fighters, and like it's a bit of a reluctant compromise just so the 'normal suspects' can show up again, because people are bitching that they're not there. 

Quite Frankly, I feel like saying it's my damn game, and I'll have the planes I want in it, and if they're not ones you want to fly, you don't have to play.
