I'm not even into git-stash, but it does sound like it solves the
problem, which is _restoring_ the conflict after you unstash. Since
you have all the unmerged entries in the merge (which is stored in
some stash ref), you can safely destroy all conflicts in worktree and
put it back to a clean state. When people want to apply the stash, you
re-generate the unmerged index from the octopus merge.

yes, but because you can restore it later now, you can remove the
conflict safely. That's what git-stash is for.
