Reject default message when Merge Request is Accepted
Description
Today we have no rule for how a commit message. Some people are very eager to Accept Merge Request after they've got Approval, and therefore forgets to change the Commit Message. So we need to apply a Push Rule which rejects the default message "Merge branch 'feature/xxx' into 'develop'.
Proposal
Is it possible to have a negated Push Rule, saying that no message is allowed to start with "Merge branch"?
