What happens when you rename "magit" to "foo" in that branch and want
to check out an older commit of the same branch? That is one of the
reasons why that belongs in to a checked in .gitmodules and not

If you don't want that either don't use submodules or set the ignore
config so you won't be bothered with any changes to the submodules.
Floating up to the submodule's tip can be easily achieved with a
script (possibly checked in in the superproject). You loose the
reproducibility by doing that, but that's what you asked for. No

You cannot access a nested sub-submodule without its parent telling
you what submodules it has. Otherwise the first level submodule would
not be self-contained, so you'll need to check it out too to access
the sub-submodules. Nothing to fix here either.

To me your proposal is trying to fix non-issues and breaking stuff
that works, so I see no improvement.
