I realize that I've not been careful enough in my language.  The 
problems I'm trying to address are just as applicable to non-C clients.  
In fact, I've written a Python client library that makes uses code 
generation:

http://repo.or.cz/w/qemu/aliguori.git/commit/a101de2ff0781795f4f7c64ece6e3d48b5783627

It's much simpler than the C interfaces because Python has a bit more 
awesomeness than C.

The only properties of the Python interface that are different than the 
C is that adding optional parameters to a command handler works okay, 
but adding optional parameters to a signal still will not work.
