I totally agree, I would hate to see us define yet another tunneling eap method 
if we could add a couple extensions to a existing one that has received 
reasonable adoption already.
 
If it turns out we had to define a totally new non-backwards compatible 
protocol I would agree we would probably be better off starting all over but 
from my read of the current (expired) TTLSv0 document I dont think thats where 
we would be going.

I would agree that "versioning" is not a good idea.  However, as I
understand it, EAP-TTLSv0 is the only deployed version of TTLS; v1 has never
been implemented.   So currently there is no versioning issue with TTLS, and
if possible, it would be best if the IETF would not create such a problem.

It is not clear to me that EAP-TTLS needs "versioning" in order to enable
addition of new features in a backwards compatible way, since it already
supports a TLV-based extension mechanism.
