Hi Mark,

Presently there is a reference to "content optimization", but it's not very clear whether this includes transparent caching.​ I think the impact of HTTPS on ISP transparent caching should be clearly acknowledged and the TAG should explain their rationale for accepting this as a consequence of the proposed transition.

I've added some text here:
  https://github.com/w3ctag/web-https/commit/f9c53a41accb892cad63358811e8d88d218f4d00

Note that there's a distinction between "normal" shared caching proxies and "transparent" (more formally, interception) proxies.

The latter have long been condemned by the IETF, and are effectively a loophole that some networks have exploited. Closing that loophole is going to cause them some pain, but they can't say they're surprised by it (the writing has been on the wall for some time).

Cheers,
