So I'm sure you've explained to the firewall vendors they should be selling proxy boxes instead, and they've listened to you. Sorry the market has dictated solutions you don't like. Time to move on, and stop fighting a battle that's been lost.
The type of firewalling you talk about only happens in less than 1% of the sites connected to the internet. As a rule, these firewalls break lots of legitimate stuff such as ECN, the window scale option, path MTU discovery, etc, etc. The people who use them are welcome to these problems; it would be ridiculous for the IETF to work around this intentional breakage.
As I said before, if you want to meddle in the middle, do it right and say you don't support this stuff rather than play coy during the setup phase and break sessions once they're established and start using the newer features. (Although I wouldn't exactly call RFCs 1191 (1990) or 1323 (1992) "new".)
