The NAT traversal angle is honestly the most compelling part here, WebRTC's ICE/STUN/TURN stack handles weird network topologies pretty gracefully without you having to think about it.

That said I think spzb's point is real, the signaling server is still a trust boundary even if the p2p channel itself is encrypted. Tailscale sidesteps a lot of that by having a more battle-tested auth model tbh.

On the "why would you even want this on phone" thing though, I guess I disagree a bit, I've been building something related: Xtro, terminal + source control + AI agent on iPhone connected to Mac, and like the use case is surprisingly legit once the layout is actually designed for mobile. Emergency deploys, quick fixes, that kind of thing.
