Are you suggesting NIP-29 should support both traditional nip-29 groups and relay-based groups? These seem like fundamentally different concepts. Aren’t they? 

 > compatibility with NIP 29

How? 

 I opened a few PRs that should allow me to retrofit relay-based groups onto NIP 29:

https://github.com/nostr-protocol/nips/pull/1604
https://github.com/nostr-protocol/nips/pull/1601
https://github.com/nostr-protocol/nips/pull/1602
https://github.com/nostr-protocol/nips/pull/1603 

 Are you planning a tgfn episode about relay-based groups? 

 I don't like interviewing myself, but I'll think about it 

 that’s something id listen to. 👍
