> I've had sketchy experiences getting a connection between two specific peers though. I presumed it was NAT traversal being finnicky.

And that is probably are IPv4's flaws, not BitTorrent. If everyone switched to IPv6 then they can connect to each other without using NAT, because IPv6 address space is so big everybody on earth can have their own unique IP address.

People would still have to open a hole in their firewall, and then we’re back to people implementing UPnP

At least on IPv6 people know it's caused by their firewall, which they can fix on their own.

On IPv4 you don't know if your packets got dropped because of your firewall blocking some ports, or because ISP's CGNAT get overloaded and decide to drop your packets (and customers can't do anything to fix that)
