pyright currently supports this in configuration as a global flag that effectively makes override apply to all classes. reportIncompatibleMethodOverride is setting and I have it on for 100k line codebase and have rarely seen cases where I disagree with rule. I can always use type: ignore if needed. I prefer that solution over an override decorator. Most classes in my codebase I consider overriding and changing supported signature an error. I'd rather make incompatible override case require comment/explanation than mark cases where override rule is enforced.

Mypy also automatically detects incompatible overrides. I can't even see a flag for it so looks like a default rule mypy applies. Here's an example with mypy enforcing rule by default, https://mypy-play.net/?mypy=latest&python=3.10&flags=strict&gist=d3e1a06857e4c6f1c698b7fa89e22f40.
