Yeah, and then let's "leave room" for adepts of documentation to add
it if they feel like it, and for adepts of Lisp style to fix the style
of the code someone else installed, and for adepts of clean design and
implementation to clean up after others, etc. etc.

We have some conventions and some standards in Emacs development, so
I'm surprised to hear that some of them are left to "adepts" to
uphold.  If we go that way, there are good chances that some things
will never happen, because no adepts were in supply, or because we
forgot, or for any number of other reasons.

I'm sure frequent users of Magit disagree.

Of course, that's not why I mentioned Magit: I mentioned it because if
we want to cater to a single VCS, a very good solution for that
already exists.
