Squash merge would be most useful in cases where someone turns in a PR and then there's back and forth which result in them making additional commit such like "Fix typo" and "Change struct name". That's not useful history and it's sometimes easier just to squash merge rather than give the contributor a lesson on reabse every single time. Naturally you shouldn't squash if the history needs to be cleaned up manually but it's rare to have multiple authors on one PR.
