Can you describe some use cases that this would enable?
Just drafted a NIP for audio files, interested in feedback nostr:nprofile1qyw8wumn8ghj7cn4vd4k2apwvdhhyctrd3jjuum0vd5kzmp0qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qpqyfg0d955c2jrj2080ew7pa4xrtj7x7s7umt28wh0zurwmxgpyj9ssqqr8g nostr:nprofile1qyw8wumn8ghj7cn4vd4k2apwvdhhyctrd3jjuum0vd5kzmp0qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qpqxv6axulxcx6mce5mfvfzpsy89r4gee3zuknulm45cqqpmyw7680qn02qk6 nostr:nprofile1qyw8wumn8ghj7cn4vd4k2apwvdhhyctrd3jjuum0vd5kzmp0qy2hwumn8ghj7un9d3shjtnyv9kh2uewd9hj7qpqyauhh489aefdkzsewe5vj2u68elzxlsln7nn5yxr34e3c22vljdq3ajwwm
Discussion
I personally want to add a music feed from a pubkey (or list) to groups in Coracle. I would pull from wavlake, but there's no way I know of to filter by pubkey because they publish on behalf of their artists. Zapstr does pretty close to what I want, so I drafted the NIP using their event kind with compatible tags.
We have the same end goal. In the meantime I think that creator tag in your proposal could be a good enough bridge to enable what you'd like to do (which is follow and filter by artists, I think) until we get there
