If you don’t specify a relay, you’ll need a relay discovery mechanism—and that’s also not very friendly - for example, an initial relay list is needed for initialization, or the user needs to configure the relay list, etc.

Because the relay *is* the group. Discord calls their groups "servers", I don't see why this should be so confusing. NIP 29 has poisoned everyone's minds by putting every group on groups.0xchat.com I guess. I want a more sophisticated type of group where admins have more control.
