I have two proposals:

(i) Tell Junio you would like the changes to stay in pu or next for now.
But he will probably do that by default anyway. :-) Thus, you do not
need to worry about them getting into a release any soon, but you will
still see some real-life testing (in theory).

(ii) When introducing new interface, introduce a user to it right away.
So, if I were you, my roadmap would be something like:

	(a) Make Git.pm use gitweb's config parser
	(b) Add 'use Git' to gitweb and convert all Git calls possible
	(c) For the rest, introduce the necessary methods to Git.pm,
	    one patch per method (I would even bundle the Git.pm
	    addition with the gitweb changes)

I'm not saying you _have_ to do it this way, but I believe it's one of
the smoothest paths. Me and I think many others of the Git project are
huge believers in "small steps" instead of "grand designs"; you will be
getting immediate feedback about your changes as you go and your work
will be useful at any point of time.

(I would love to provide feedback and review your patches, but please
note that at the same time I cannot promise I will be able to do it all
the time; I have failed these hopes in the past already, and again
likely will in the future.  But hopefully there's plenty of other Perl
hackers on the list.)
