Meaning, that if we switch from h1/h2 to to h3 (on the same host and port) we'd specify an identical host + port and it can't be used for loop detection etc. Further, the Alt-Used header says the port number is optional. But what does it mean when you don't specify the port number? We don't provide a scheme or alpn to aid. It seems at least Firefox thinks no port implies port 443. We found a service that didn't like when curl *includes* port 443 in that header when going from h2 port 443 to h3 port 443... -- / daniel.haxx.se
