Totally agree. We ended up with "HTTPS" by allowing concerns regarding
number of bits on the wire to override those concerning clarity.

An earlier version was an overly verbose `prefer` header, which Ilya shot
down due to caching concerns (e.g. `vary: prefer` would have bad results as
it's tied to the whole header value, as opposed to the specific preference).

Still, this is a totally reasonable direction to move in. If we're fine
with the length, then why not `upgrade-insecure-requests: Totally
supported! Gimmie that HTTPS, please.`
