Allow comments on a commit message
Proposal
Commit messages are important for debugging, more than MR descriptions for example, as commit messages are recorded to the repository. GitLab makes it hard to comment on the message though, and leads to developers not reading the message during reviews. As example, say I wanted to comment on the commit message of deadbeef, now I'd create a note:
I think X can be improved on your commit message of 'deadbeef'. When posting this, it can't be auto resolved, and I'll have to manually check if it actually improved. Just the OID for the commit changing could imply the commit was rebased, or the wording was actually updated. THere's currently no great way to ask for improvements nor for verifying they took place.
