Btw: I wrote something about proxies i would like to amend:

In a prior life, we IETF standardized IP Multicast SSM which does require
application upgrade (signal S,G), and then we and other vendors implemented
what we call "SSM mapping" to work around that (not requiring application
update). Call it an SSM proxy. No vendor brought this into the IETF
because we always wanted to see this positioned as a temporary transition
technology and not make it too attractive to run forever. 

Now, you don't want to know what really is deployed in networks and what
strategies customer apply. Lets just say that SSM mapping is very successfull.

So, to a degree you can account my above paragraph either as 
"famous last words" or "don't give up the good fight". So i am all for
standardizing any proxy methods the IETF thinks makes sense to standardize.
