Your feature request related to a problem? Please describe

Following #5339

• feat: new linter exclusions system #5339

Where an option was added for linters (very useful BTW)

There is a new option linters.exclusions.warn-unused that emits a warning if a linters.exclusions.rules or linters.exclusions.paths is unused.

I would like to get the same things for formatters

Thanks

Describe the solution you'd like

I would like to be able to report unused formatters exclusions via formatters.exclusions.warn-unused that emits a warning if a formatters.exclusions.rules or formatters.exclusions.paths is unused.

Thanks

Hello, the way to handle exclusions inside formatters is completely different from inside linters, it's not really possible to detect unused exclusion paths.

FYI, formatters.exclusions.rules doesn't exist.

OK thanks indeed

🤔 maybe I can do a hack, I need to think about that.
