It makes them better, up to a point. Many commits (esp in private repos or WIP branches) are barely descriptive and of the form "stuff broke" "i got test to pass" "yay", etc. These commits don't make it into mainline, and I don't really want to spend time carefully writing them. In this case, a tool like this may be useful.
Also, the `aicommit` tool has a -c flag for accepting context and the "why". I have only been playing with it for a couple of days so I'm not sure how effective it will be.
