It's even worse than that. P2P means that connection differences between peers also makea difference. User A might see users B and C, but user B might on see A due to a connection difference between user B and C. It is very annoying to enter a group chat and hear:
User B: Is user C's stream dead for anyone else?
User A: I see user C.
User C: Sorry, what? I'm right here.
Honestly, other than a 1-1 chat, I can't think of a situation where p2p is worthwhile. Even then, it's almost always better to use an SFU.
