Steam sockets and CloudFlare's UDP forwarding really are different though. They provide ddos protection as well as route optimization due to lots of points of presence.

Here there seems to be no mention of ddos mitigation or shorter routes due to infrastructure. Yes you need a key to connect but your iroh relay server can still be attacked. I suppose you could roll your own distributed anycast system for this.

I assume that the 'enterprise' relays have ddos protection. DDoS protection also comes standard these days, but we've seen attacks go from 20gbps to 20tbps so if uptime is required then tough luck.
