I was annoyed by a lack of support for git worktrees in my current employer's dependency system (think virtualenv from python, but for everything). I fixed some scripts to be worktree dependent and tested it out thoroughly on the CLI, but as soon as I got the PR through with the change, I got a bazillion messages on Teams from people yelling at me that I broke their workflow.

Their workflow was basically "blindly point and click in Visual Studio because I don't understand even the basics of git. I miss the old custom in-house VCS and am very grumpy".
