It's already supported for Git, actually, on master.

You make an interesting point.  At the end of a multiple commit
cherry-pick, we could display a non-shortlog Log View buffer with just
the result of the cherry-pick, and display a message saying "You can use
\\[log-view-modify-change-comment] to modify any of these messages".
That might be perfectly adequate and also means that when you don't need
to make any edits, you're already done.

Potentially, though I think full interactive rebases are probably
out-of-scope for VC because they're highly VCS-specific.

Yeah, especially when one is used to a full Log Edit buffer for editing
commit messages most of the time.

Yes, I agree, vc-revision- for all of them.
