I call that weaponized dogmas. It’s at least better than people who insist on being DRY by writing an inscrutable generic helper function which will only save 3 or 4 lines of code duplication.
When you discover it for the first time, you think, "huh, neat, why not use it". Before you know it, nobody can reason about your code and if you leave, nobody wants to maintain it (esp. if your test suite is not extensive).
I want to read and write the language I'm developing with, not the helper methods of some overeager developer who wanted to leave his mark on the codebase.
