Ideas for supporting this case (i.e. the "I want to do HTTPS to my
router" problem) in browsers have done the rounds a few times. The
reason that nothing has happened is that it's a lot of work to do it
right and it's unclear that we would be able to get a useful mass of
devices supporting such a scheme. The mostly likely outcome seems to
be that we would end up with a complex addition that's rarely used and
thus doesn't justify the cost.
