GitLab offers this as a merge option, and I really dislike it for this exact reason. Worse still than not knowing which merge is associated with the commit is that you can't even tell the difference between reviewed commits and those which were simply pushed directly to master.

IMO it's far preferable to have an explicit "merge" commit referencing the PR in question, whether that that is a --no-ff merge or a single linear squashed commit.
