I agree with Phillip's follow-up that the `pick <original-merge>` syntax
would pose a problem, but for different reasons: We already tried it, with
--preserve-merges, and it is just a really stupid syntax that does not
allow the user even to reorder commits. Or drop commits (except at the
very end of the todo list).

As to your concern: The ultimate commit hashes do not have to be known
until the merge commit is rebased. The current approach is to use labels
for them (`label <name>`), which Simply Works.
