"ALL" should ignore deprecated rules

[philippgl]

It would be nice, if --select=ALL would ignore already deprecated rules.

I think, situations, where you select "ALL", but do not want to ignore already deprecated rules are rare (but this is just a gut feeling).

see also #9778

I don't think we can have deprecation be a breaking change i.e. a rule turns off when it was previously on. It's an interesting idea though.

I think it would make a lot of sense to deselect these in preview mode (if we don't already? I think we do?).

[philippgl]

It is turned off in preview mode. But I guess, that "ALL" can break already by enabling new rules, so breaking is expected, if using "ALL"

From https://docs.astral.sh/ruff/linter/#rule-selection:

Use ALL with discretion. Enabling ALL will implicitly enable new rules whenever you upgrade.

Hm that's fair... I do prefer this to #9778 so okay let's do it :)

I'm going to assign myself but if anyone is interested in grabbing this feel free and I'll just be the reviewer.

@zanieb Hi! Can I take it?

[zanieb]

@WindowGenerator go for it!

[philippgl]

Wow, thanks. This is just my second issue here and I have to say, that you are as fast as ruff...

[marc-benz]

Could it also make sense, to add a configuration option in the pyproject.toml that automatically ignores all deprecated rules? Or is this already possible.

[zanieb]

@marc-benz That was discussed a bit in https://github.com/astral-sh/ruff/issues/9778 I guess? I'm pretty hesitant to add that though. They'd also be ignored by switchingpreview on in your config.
