Ok, how's this then....

This reminds me of DNT which was one we passed on when it
was brought to the IETF and I think we should be glad we
did that.

Now I *think* there are fewer adversaries in this case and
those are maybe less adversarial but this has the same
property that there's no technical enforcement mechanism
at all, which makes me wonder.

That said, this might be an ok thing, I guess.

I'd prefer if IEEE provided me a way to have my (E)SSIDs
etc. look random every time to non-authenticated devices
or something. Or to have a way to have us all easily be
able to share a few SSIDs and MAC addresses. There are
probably loads of reasons why that'd not work, but if it
did at least then we'd not just be depending solely on
the kindness of strangers.
