git-bug's author here with my 2cts. For what it's worth, I was aware of git notes during my original design process, but I found them clunky. I realized they would not be enough on their own to do conflict resolution and I'd be better making my own data structure with regular blobs, trees and commits. But when you have that, there is pretty much no point in using notes, as that would just grow the required features on which you sit on. What if I want to port git-bug to mercurial or whatever comes next? Even metadatas (the natural point of notes) are better expressed within that same unique data structure. Additionally, you then only need to sign those commits to cryptographically lock everything.
