The latter may probably be better.  

After cloning the superproject, you show interest in individual
submodules by saying "git submodule init <that submodule>" and until
then your .git/config in the superproject does not indicate that you
are interested in that submodule, and you won't have a submodule
checkout.

"deinit" is a way to revert back to that original state; recording
that you are no longer interested in the submodule is the primary
effect, and removal of its checkout is a mere side effect of it.
