Against shell and perl yes, not against the rest.

Seems sensible, but I don't know what "rejection" would actually mean.
My "extensions" are on the way to the contrib area. Is the contrib
area supposed to have different rules? I don't know.

Either way, making a script work on python 2.6 is probably easier than
trying to "reject" it.

Too late.

I don't see what this means in practical terms. People are going to
write code in whatever language they want to write code in. How
exactly are "we" going to "encourage" them not to do that is not
entirely clear to me.

I don't think there's such a thing as "git leadership" that would be
able to take these policy decisions, and if there was one, I don't
think the evidence presented would be enough to weigh in either way.

Subcommands are also probably more efficient in c. And lets remember
that most people use git through the *official* subcommands.
