As always the problem isn't the actual thing being discussed - the problem is shitty developers who wrote shitty comments and/or don't update comments when they update code.
Good and up to date comments are good and up to date. Bad and outdated comments are bad and outdated. If you let your codebase rot then it rots. If you don't then it doesn't. It's not the comment's fault you didnt update it. It's yours.
Guard rails should be there to prevent inexperienced developers (or overworked, tired ones) from committing bad code.
"Try to think how to refactor functions into smaller ones and give them meaningful names so that everyone knows immediately what's going on" is a good enough guard rail.
