Me too. The main issue is how to implement the upgrade path for "old" 
scores... Graham said a while ago that he has some ideas, but he hasn't shared 
them yet ;-) 
My idea is to:
- -) rename cresc etc. to deprecatedcresc etc.
- -) write a conversion rule \cresc->\deprecatedcresc
- -) implement the postfix crescendi with the names cresc, dim, decresc

I don't see any other way to change the \cresc from prefix to postfix style in 
existing lilypond code, since you can't rely on a single note following 
immediately after the \cresc...

Cheers,
Reinhold
