You know what, never mind.  I'm still going to write the Web-SIG so they 
know the change is coming, but this is really a very minor thing; just a 
feature we won't get "for free" as a side effect of PEP 325.

Your decorator idea is a trivial solution, but it would also be trivial to 
allow WSGI server implementations to call __exit__ on generators.  None of 
this affects existing code in the field, because today you can't write a 
try/finally in a generator anyway.  Therefore, nobody is relying on this 
feature, therefore it's basically moot.
