Yes. Everything inside a submodule is owned by that submodule, so the master repo can't know anything about it. You can have a submodule which in turn has submodules though. If you couldn't, it wouldn't be possible to checkout only the framework1 repository and get all its dependencies.

I have no idea what problems you run into with more than 2 tiers of submodules though, but I guess that's for you to find out and report about.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
