When reviewing suggested edits, if one clicks Approve, another user still has to approve it before it goes live.
However, if one clicks Improve Edit, the edit is instantly applied without needing a 2nd review.
So I ask, why does a normal approve need two reviews?
Approve
requires the reviewer just a single click and not much thought, whereasImprove Edit
requires actually some work and the reviewer has to think about what they do. That way the system probably prevents robo-reviewing.
