This makes me think a nicer (and simpler) implementation could be just special comments that have a shell command in them. Then your ci script recursive greps for commands, and runs them. That way you get enforcement in ci, not for devs, and also a super simple system with no complex compiler magic. Bonus point: it will work in any language.
