Ah, this is great! It's a step towards solving my biggest complaint with PEP 723 scripts: bad editor support.

I loved the idea on paper, but without manually creating a matching venv & installing my deps, I wouldn't get in-editor completions during development. That was fine for small things, but intolerable as the script grew. So it's still not a feature I've used much, since it made more sense to just make a real dev environment.

I'm glad to see there'll be improvements here!
