Sorry for the late reply here as well…

I’m in favor of adoption here, from a CDN perspective these mechanisms are critical. As I think has been pointed out already, in the Mozilla statement and maybe others, there are some wrinkles around how to deal with this “double lookup” mechanism; you have to have the No-Vary-Search response header before you can do the final cache lookup.

If adopted, working out those details would be required.
