Right, I guess that I had assumed that you hadn't made that leap yet.
As in, clients would not be able to expect a good certificate if they
had followed their noses to the other end of an http: URI.  That was
kinda the point of the rest of my mail: there is no point in raising
the bar that high because all that does is chase people back to 1.1.

The one thing that worries me a tiny bit is that a browser's position about what an acceptable mix of security characteristics might change over time, and if it does, we may need this distinction again. However, since we're using draft identifiers, it's not a huge risk.

I think that there will be a continuing evolution of what the security
properties of each of the schemes is.  But I hope that this isn't
going to lead to states of disconnect where each end has very
different expectations.

Maybe we can eliminate the differences; I remain a little skeptical
about that though.

Noting that the distinguishing mark here is the 's', sure.
