I agree with your footnote -- the more general case will require a

Ramkumar Ramachandra is making progress on such a thing right now!
That's great news -- this is a project that has been attempted at
least four times, by five people (including me), in the last three
years.  I hope to see this round make it in -- I was actually thinking
about returning to the problem after seeing this series through, but I
would be glad to see Ram beat me to it.

[Hello, Ram!]

Hmm, on further reading I'm not sure the sequencer Ram aims to build
this summer actually extends to the "mark" and "reset" commands (or
the concepts of "the rewritten <commit>" and "detach" in the
pseudo-TODO notation of your footnote) that would be required to
implement this broader rewrite-side-branches feature.  It looks like
the focus may be on taking the existing features of rebase and
bringing them into C.

This sounds great too -- it should make rebase a lot faster -- but it
will leave open the pet project I've thought about returning to, of
making "rebase -i -p" work correctly even when the user wants to
rearrange the commits rather than just s/pick/edit/ etc.  That will
require implementing a richer sequencer very like the one required for
a general rewrite-side-branches feature.

Ram, have I correctly read your plans?  For context, see Junio's
remarks upthread about one thing a richer sequencer could be used for:
