I can sympathize a bit with nostr:npub1qfkcklnmes45z75y7y8dkud5yll8vp5eq5ysk9rmgqdxeasv8unsrfj6kq's frustration. When I built my desktop nostr client I found myself doing a lot of reverse engineering from other clients and apps. Particularly when I added support for NIP-51 lists; I remember it being unclear whether to use kind 30000 or 30001 for a list that has both people and events. So I just looked to see what existed in the wild and figured there’s my answer.

Also, it was unclear whether importation of items using the a-tag should be recursive but I couldn’t find anyone who had implemented it so I just did what I thought made the most sense. (Yes to recursive.)

But I also understand that every additional detail that fiatjaf adds to the nip repo is another opportunity to piss someone off, and/or potentially to lock something in that we later discover was a bad idea.
