I guess.
So the repo tool has the concepts of groups. I plan to add that to git
eventually, too.
i.e. with comma separated list that looks like:
git clone --submodule-groups=default,x86builds,new-phone-codename
Having a new option there there I would also set the
submodule.autoupdate=all
implicitly which then enables --recurse-submodules on all supported commands.
By introducing such a new submodule groups option we don't need to tell
the users about all the new submodule options, but they can still take
advantage of them,
I'd assume.
Does that make sense, too?
