This seems worth a little bikeshed paint.

I appreciate that "HTTPS" and "TLS" are short, but it seems like that comes
at the cost of having any semantic content.  Without staring at the spec
for a few minutes, I have no idea what these mean.

Is it accurate to say that the goal here for the UA to indicate that it
supports upgrade-insecure-requests?  So that the server knows that it's
safe to upgrade this client even if it relies on u-i-r to make HTTPS work
without mixed content problems.

Perhaps we could borrow a page from SIP here [1], and use something like
"Supported: upgrade-insecure-requests"?
