ok, let's drop that patch then.

I think the branch handling would be the difference. I'd expect
"merge --recurse-submodules" to be sensible about staying on
the branch both in the superproject and submodule, whereas
"submodule update --merge" is too much plumbing, that we'd
expect a sensible branch handling (detached HEAD is just fine,
right?)

The merge result would be the same, I'd think.

What do you want to do in revert --recurse-submodules?
When you have "revert --recurse-submodules $COMMIT",
would that revert all submodule commits introduced in
that commit as well as the regular superproject revert?

This would require either opening multiple editors
(once per submodule and at last for the superproject)
or we'd have to do fancy snip-snapping of the user input,
e.g. providing a template like:

    Revert "$title"

    This reverts commit $COMMIT.

    # The above is for the superproject commit
    # Please enter the commit message  ...
    #
    # Changes to be committed:
    #       ...
    # --8<-- DO NOT DELETE THIS LINE
    # Below is the commit for submodule $submodule:
    Revert $submodule_range

    This reverts commits $maybe_many

    # The above is for the submodule commit
    # Please ...

I guess it may be easier to just have multiple
editors opened sequentially to give a commit
message.

Not sure what you mean there?
