Yea the structure matches what you said but not really using the set of words called out in that example like "feat" "chore" etc.. Personally I find that less useful than categorized tags that the developers just choose as they go along and are meant as a thing to help you read the commit, not to actually fit into a perfect index of possible tags that are controlled someplace. Here's an example of the categorization scheme in use (plenty of other examples out there). https://gitlab.freedesktop.org/mesa/mesa/-/commits/main
