I think you missed my point with this change. There are several
reasons for external commands:
1) it allows you to customize bzr for your own weirdness,
2) it allows you to fill temporary holes in bzr functionality generally,
3) it provides a simple entry point into bzr development,
4) it allows Martin to see what is missing in bzr, and
5) it allows Martin to push off niche features into "contrib".
(2) is most pressing for me now: I can implement "bzr push" *for my
project* in a one-line shell script ("rsync...."). Implementing that in
python is just silly, and of no use to Martin. Similar arguments apply
to (1): they have to be rewritten anyway to be general, so the initial
language is unimportant.
(3) is also important for the vitality of the project, but in the short
term it's better for Martin to be writing the missing infrastructure
than arguing over minor patches. (4) and (5) will become important
further down the track, a-la netfilter's patch-o-matic.
Now, I think a python extension facility is a good idea, any maybe this
will suffice, but forcing extensions to be in Python undermines the
effect of this now.
Hope that clarifies why I think this is so important,
