Is "Auto-cancel redundant, pending pipelines" active/useful?

I noticed that when committing a typo fix right after another commit in an MR, the former pipeline remained running. In case the above setting is not active, should be activate it in [Settings > CI/CD > General] to free up runner time & conserve energy?

There might be a small risk that the cancelled pipeline would have helped pinpoint an issue more directly to the 1st bad commit than if the next pipeline encounters it as well, that the problem of leaving redundant pipelines running is larger.
