I think calling WebRTC a behemoth is a bit of an understatement. Excuse my sharp-tongued criticism, since I understand a lot of hard work has gone into it, but WebRTC has no regard for interoperability. As of now, it is nothing more to me than a VPN deanonymizing exploit.

WebRTC leaks true IP addresses unless it is outright disabled in [supported] browsers. It is a huge annoyance, and I would be hard-pressed to view it as more than a gimmick that complicates the already messy landscape of web development.
