Here we cross the tricky line from "upstream does not maintain it, so
it's definitely crufty" into "I don't see why someone else should not
have moved from 2.6 to 2.7, so let's nuke it".  As always, we don't know
what people are doing that isn't in pkgsrc (using python from pkgsrc).
And migrating systems takes time - I know of multiple boxes with 26 in
use, even though they could be rebuilt to 27.

Right now I don't see what harm python26's continued presence is
causing, and I object to a general approach of "I don't use that any
more so let's delete it".

So if we want to announce that it will be moved after 2013Q2 is cut, to
avoid having a branch or head with a version not supported upstream,
that seems sensible.  But I don't see any justification for rushing into
it now.
