Most apps on the web break this, and they seem to be doing fine. As are we.

No they don't. When they don't recognize how GET is used outside of 
ivory towers, there has been a huge outcry and they've been fixed, as 
with the Google Web Accelerator.

Something I think will hinder its adoption, if it remains so enamored 
with HTTP verbs. There was recently a discussion about relaxing the 
restrictions to allow most APP functionality through POST, though I 
didn't follow where that ended up.

(Tangent.) There has been a disturbing disconnect the past year or so 
between the real world and people writing standards and languages. 
Trading convenience and backward compatibility for academic perfection 
is the reason things like PHP5 and XHTML 1.1 have been abject failures 
in the marketplace. (Single-digit adoption rates.)

I don't see any connection.

BTW, it has already been demonstrated that switching everything to POST 
would not solve the problem as completely as secure nonces would as you 
can still cross-domain submit forms. Therefore it would be a lot of work 
that would, at best, please a few pedants and bring us into SHOULD 
compliance with a 7+ year old standard no one else supports either.
