Sorry for being a buzzkill here,

but I don't really like this except as a temporary/transition solution.
Assume CGRAN really takes off and grows. Do you really want all OOTs out
there in a single repo? What exactly is their logical connection, which
would warrant them all being tied together in a super-repo?
This would require someone to keep updating the submodules, too, which
seems unnecessary.

In the long run, I would assume people want to host their OOTs on github
(or similar services), and CGRAN would simply be a link to those.
As I said, during a transition time, we might want something else.
But submodules are messy, and I suggest not using them for this
particular application.
