Sorry, my last sentence in that above paragraph was misleading. There
was a discussion at Zurich about how user agents felt about trusting
proxies to snoop on https traffic, and all user agents present (I
mentioned them already) did not support it. You're right, we didn't
discuss this *specific* proposal here. I will let other user agents
speak for themselves here. My point is, if no user agent supports this
direction, then I don't think we should standardize, since I don't
think we'll have running code.

You ignored the conditional in my statement. I shall repeat it. *If no
user agent plans on supporting this*, I don't see the value of
standardizing it. You may reasonably argue that user agents *should*
support this. Therefore, I'm asking if there are user agents that
support this.
