I can only speak for myself. In the roughly 12 years I've been using git at multiple different companies and for my own projects, I have never used git submodules. I feel like I have a good, well rounded set of experiences too. Code bases big and small, massive monorepos, and many microrepos all separate. In none of them have we used submodules.

That being said, maybe submodules would have solved some problem here or there that we had. I'm open to arguments in favor of them in that case. But we've always been able to get the work done without them, so I don't personally think they're indispensable.
