SAME exact experience here. If you can create either a build workflow or some other method of managing a relationship like this, do that instead of submodules.

I've been on teams that used it quite excessively and it was a PITA. I've used it in much smaller ways to try to avoid a build step or two and it worked until it was responsible for the world falling and no one knew it was that damn sub module. Just because the tech exists, doesn't mean it's a good idea.
