The optimization opportunity of this may be a lot smaller than you
would think---you must cater to not just exec but hook scripts that
are run while a new commit is made, which means every step you'd
need to write anyway.

Would that break external scripts, hooks, etc.? I am not sure if we
even have any rough consensus for allowing other people to peek into
the .git/rebase-*/ directories, but I am inclined to say that it
sounds more like a solution looking for a problem than a good idea
to solve some concrete problem.
