This. As a user and a developer I've had more than a few run-ins with a distro deciding to be a bit different, usually with no very weak justification (pedantic interpretations of some standard, attempts to make something 'neat', or just random changes that someone thought would be cool). Debian is especially bad at this, Arch tends to be better but they've also done some stupid things (python-as-python3 being a thorn in so many developer's side for years).
