WebRTC is peer-to-peer so there's no additional network latency from the protocol. There's the TURN fallback for when the participants can't reach each other, in which case bouncing through a proxy is the best you can do anyway. (If some implementations have high processing latency on top of the network latency, this can be fixed without changing the protocol).
