You don't need domain names to make Communities work. I don't want to rely on one relay domain for Community IDs or the publication authority of members. They bring all this obvious attack vectors and allow for about zero flexibility. I want to able to optionally set, per content type: - a feVertex etc...) - a list of "roles" that can publish that content type - a retention time - exclusivity to that community VS interoperability with others NIP-05, NIP-29, NIP-72, ... all don't even come close to allowing for that. #communikeys do.
