... 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:

    http://www.usb.org/developers/devclass_docs

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...

I have no plans for my browser to support that, and I don't think Google servers will support it either, because we care strongly about the advantages of TLS-ALPN vs Upgrade.
