I have heard about nostrocket on your pod. Great idea albeit ambitious.

I just checked the spec for NIP-1971 and it looks more like a replacement for complex issue tracked used internally within companies (like Youtrack, altassian, jira, zendesk, redmine) more than GH issues (which are rather simple).

Would love to see it to fruition! For now I will focus on bridging NIP34 events, gotta start small.
