In general, I would say that we shouldn't do anything that's
gratuitously backward incompatible unless there's a good reason.
However, if it helps us, I don't feel like we need to go too far out
of our way for stable distributions older than N-1.

I think it's very important to make sure that upgrades from the
previous stable version work, but I'd say the importance diminishes
substantially after that.  Here, I was actually speaking about Debian
stable releases, but I think the same probably applies for emacsXY
versions as well.

Also, I'd like to drop emacs21 as soon as we can after lenny.  In
truth, it probably shouldn't be in lenny, but my attention was tied up
elsewhere during what was supposed to be the critical period.  Of
course in hindsight, given the lenny delays, that might not have
actually been the critical period...

I'll look over your work in the next week or so (plus or minus holiday
distractions), and then post comments.  I'm certainly in favor of
fixing up emacsen-common, and I should be in a better position to
help.  Also, since these changes won't go in lenny, we should have a
reasonably free hand.

Thanks very much for the help.
