I was just checking into your bug report.
Are you sure about the Stunning Fist thing? There are lots of Monk Bonus feats (Diehard, Improved Trip, Combat Expertise, etc). All of them can be taken as normal feats, as well as slotted in the bonus feat slot.
If SF can ONLY be slotted as a Monk Bonus feat, that would make it an outlier wrt all the other feats.
