If I had to guess, I’d say submodules. I work on a couple of projects with no submodules and find work trees great for those, but incredibly painful for the projects that have them. This seems to be getting better in newer git versions, but for a long time basic things like removing a worktree just flat didn’t work with populated submodules.

Submodules are such a pain in the ass. None of my own projects use submodules but when I work on open source projects they never seem to work as expected.
