... and don't forgot some of the more obscure usage of HTTP, such as HTTP over USB in the USB-IF's IPP USB Specification:


There isn't much point in using TLS over USB (and a lot of cost issues for that class of printer against it), and we need to continue to use the same USB end points/interfaces, so upgrade remains an important feature of HTTP/2.0 for me/Apple...
