I agree. I'll have soon-ish the webui accept OAuth/OIDC, so you can easily host and replicate a normal bug tracker experience... yet still benefit from the other workflows that a normal forge can't have.
That's the key feature to make a distributed bug tracker actually work in practice.
Wouldn't it require constantly pushing/fetching? Or would it effectively be like a hosted thing with a service layer on top of git showing a live view of the repo's tickets? Like github but for tickets... oh wait...
