Do you actually have any specific, tangible issue with submodules?

Yeah sure. These are few that I can remember off the top of my head. There have been more:

  • Submodules don't work reliably with worktrees. I can't remember what kind of bugs you run into but you will run into bugs if you mix them up. The official docs even warn you not to.

  • When you switch branches or pull you pretty much always have to git submodule update --init --recursive. Wouldn't it be great if git could do that for you? Turns out it can, via an option called submodule.recurse. However... if you use this you will run into a very bad bug that will seriously break your .git directory.

  • If you convert a submodule to a directory or vice versa and then switch between them git will get very confused and you'll have to do some rm -rfing.

Even in the cases you’re clearly and grossly misusing them

Oh right, so the bugs in Git are my fault. Ok whatever idiot.
