Doing stuff like this in the background lets me maximize my productive time when I actually have time to sit at a computer (more limited than ever with a newborn + toddler!). I kicked this (and a handful of other tasks) off while my daughter was bathing last night.
AI is way slower at completing these tasks than I would be doing it manually, but it does them for me when I can't be doing them.
When I get to the computer, my review + commit sessions are relatively short, and then I can quickly get on with the stuff I really want to work on or that really requires my attention.
