It's like you'll also need DNS, which isn't decentralized either.
If someone wanted to write this as a WebRTC-based decentralised version there is nothing stopping them using something the like the public signalling servers that Mozilla uses for their Hello service.
Also, if some users wanted to run a signalling server themselves, that's ok too.
I get your comparison, however DNS is not actually that fundamental to P2P networks, all you need are IP addresses (at least not after the bootstrapping phase). Whereas this is making the entire connection setup dependent on these signalling servers.
You're right, there are public signalling servers and such. I just wish we weren't so restricted in setting up direct connections, such that you could do it through your bootstrapping peer in the network.
