Yeah, I understood what you mean, and I see you noticed that B4
commit, for which I did anticipate possibly bringing up a discussion
like this ;)
I agree with Jake here, my thoughts exactly (what I wrote in that
other subthread[1], too):

Hmm, I wanted to elaborate a bit here, but that sentence seems to
summarize the pure essence of it, and whatever I write looks like
just repeating the same stuff again...
That`s just it. And stopping to give the user a chance to
review/amend the result, where he might decide he actually did want
something else - so all good.
Otherwise, I would be interested to learn how context/semantics
guessing could provide a better default action (without introducing
more complexity for might not be much benefit, if any).
But in the end, I guess we can just discuss the "most sane default"
to present to the user (introduce or obsolete that new commit B4, in
the discussed example[2]), as we should definitely stop for amending
anyway, not proceeding automatically whenever U1' != U2'.
Oh, and what about situations where we introduce new or drop existing
branches (which should be possible with new `--recreate-merges`)...?
"Preserving old branch semantics" may have even less sense here - the
(possibly heavily reorganized) content is the only thing we have,
where context will (and should) be provided by the user.
And I guess being consistent is pretty important, too - if you add
new content during merge rebase, it should always show up in the
merge, period. It seems pretty confusing to find out one of the
branches "declared special" (even more if it`s based on uncertain
guess-work), so when you add something to it it`s just "swallowed",
as the whole branch is always obsoleted, for now and ever.
I might even see a value in such behavior, but only as a conscious
user action, not something done automatically... I guess? :)
