So, to makw sure I understand you correctly, you are proposing that future 
clients and servers support *all* the versions of the draft that have ever 
seen non-trivial deployment (possibly including hixie-75, likely including 
hixie-76, and presumably including more future versions that happen to 
line up with significant client releases)?
