That would only save substantial time if the pipepline is architected in a suboptimal way: Those checks should get run immediately on push, and first in the pipeline so the make the pipeline fail fast if they don't pass. Instant Slack notification on fail.

That's still multiple minutes compared to an error thrown on push - i.e. long enough for the dev in question to create a PR, start another task, and then leave the PR open with CI failures for days afterwards.

There are substantial chunk of fast checks that can't be configured in <arbitrary editor> or that require a disproportionate time investment. (e.g. you could write and maintain a Visual Studio extension vs just adding a line to grep for pre-commit)
