WebRTC supports peer-to-peer UDP connections as well. Thus it's better for use cases like low-latency games, video calling, and secure direct communication between devices.
A better push might be to make WebRTC more simple and modern, but I'm not sure if any standards committees are working on this yet.

Do you want a new PeerConnection API? Are you annoyed with the Offer/Answer model? Do you have beef with the protocols. The possibility are endless :)
WebRTC should be the universal networking primitive for the next phase of the web, but the API exposes too many implementation details – its abstractions leak.
This plus the overall weight of integrations limit mass adoption by developers.
Doesn't it require DTLS over UDP though?
