You mean Internationalized Domain Names, and specifically U-Labels (the 
thing that can actually be read the way it's intended to read, rather 
than some useless salad of letters after xn--)? I fully agree. The 
reason these are in punycode in HTTP/1.1 is that HTTP/1.1 is way older 
than IDNs, but for HTTP/2.0, that's not the case.
