Just an FYI full mesh would still require communicating with a third-party server, at the very least for initial networking when joining/leaving a group call.

The whole point of E2E encryption is so that passing data through a third party shouldn't matter in the first place. And lastly, even when you have just a 1:1 video chat, sending and receiving full resolution/quality multimedia can still be way too much for some peoples' internet connections. UX is extremely important for Signal, as unreliable video chat is a surefire way for those less caring about privacy to hop back over to a privacy-violating alternative. I feel sorry for those working on bringing security/privacy to everyone, as they have to appease power users and privacy absolutists, along with one's grandmother and the TikTok generation.
