I mean if everyone already has a way to contact their friends (discord) and say "hey let's play this game together", sharing that link does away with the need for a coordination server. But there's still the need for at least a server, even if it's just one of the clients that knows how to take charge (like Minecraft).

The link could just be encoded information that gives the hosts details for everyone else to connect to.

Yeah, I skipped over a lot of the details, but you would need someone to choose to be a "host" (at least in terms of a "host" for the connection signaling stuff), but you can also implicitly make it the person who created the link safely.

If everybody is behind NATs (without uPnP privileges), nobody can be the "host" for connection-signalling purposes.

There are public ICE/STUN servers that can facilitate NAT-punching, google even hosts one. But that's not the aspect that I thought the root comment was talking about, but more the aspect of "A is hosting a room called 'stuff', and B and C want to browse the list of rooms and connect to it".
