To be fair, I've used Poetry for years and it works/worked amazingly well. It's just not as fast as uv.
It works far more of the time than people give it credit for. There are a lot of good XKCDs, but that one is by far the worst one ever made, as far as being a damaging meme goes.
It's survival bias. You'd never see the confusion from would-have-failed standards-wannabes that xkcd927 helped prevent.
