Even non-interactive rebase may bring arbitrary asymmetric changes on
both sides of the merge, especially likely when resolving conflicts
needs to take place. OTOH, interactive history editing session could
have merges that we don't intend to edit at all. Overall, neither
non-interactive case is in fact much simpler, nor interactive case is so
much different.

Exactly. This fact hopefully won't stop us from looking for more
suitable automated handling of the general case though. It should still
be our goal to reduce the number of such aborts and to suggest better
merge result for amendment when we are still aborting.

Your proposal hopefully is such a valuable improvement.
