I haven't used this kind of +/-2 but I think it might be good communication between reviewers.

sometimes I review something and say "approved", but sometimes I can only review part of it, and really need someone else to check what's out of my wheelhouse.

sort of "partially approved".

I have used systems that can set things like "requires 2 reviewers" or "bob, fred are required reviewers, elon and sam are optional reviewers".

also we had "thumbs up, thumbs down, and some comments might have a "task" associated with them as a required fix before approval"

optionally, maybe before you say "approved" you have an overall comment, and see the comments of other reviewers.
