4. A new branch with the same name is created on each submodule.
a. If there is a naming conflict, we could prompt the user to resolve it, or
we could just check out the branch by that name and print a warning to the
user with advice on how to solve it (cd submodule && git switch -c
different-branch-name HEAD@{1}). Maybe we could skip the warning/advice if
the tree is identical to the tree we would have used as the start point
(that is, the user switched branches in the submodule, then said "oh crap"
and went back and switched branches in the superproject).
b. Tracking info is set appropriately on each new branch to the upstream of
the branch referenced by the parent of the new superproject commit, OR to
the default branch's upstream.
5. The new branch is checked out on each of the submodules.
In many cases the branch name for the superproject isn't going to be
appropriate for submodules.
This seems likely to create a LOT of junk branches. Do you also have a
proposal for cleaning those up?
