That's probably true. WSGI is likely not the best example for this
case, just the trigger murmur that caused me to speak out. The WSGI
spec is not the only place where people will take the opportunity to
break APIs. Unfortunately as with WSGI, API breakage may in many cases
be unavoidable..

I would like to encourage the adoption of any new such standard in the
Python 2.6 environment already, if at all possible. This way it's not
an extra step for people to be burdened with when they move to Python
3, but something they can prepare for gradually.

Martijn
