WebRTC is pretty hard to get right for client/server (it is designed for P2P), and may exhibit P2P downsides even when used for client/server (obnoxious NATs).

WebRTC is pretty hard to get right for client/server (it is designed for P2P), and may exhibit P2P downsides even when used for client/server (obnoxious NATs). If "dumb" client/server UDP doesn't work, your internet likely has bigger problems. Then there's the RFCs you have to implement to build it, which are more niche than you'd think. You can't do the entirety of WebRTC in Rust right now, without implementing multiple massive RFCs yourself. It's a simpler spec to solve a simpler problem. WebRTC is necessarily complex, but still overkill for a bunch of scenarios.
