Our variant of this same idea that Willem Toorop and I presented at the DRIU BOF in Montréal has a URI for the DoH case:

https://tools.ietf.org/html/draft-pusateri-dhc-dns-driu-00 <https://tools.ietf.org/html/draft-pusateri-dhc-dns-driu-00>

But let me remind everyone that there was a lot of people agreeing with Ted in Montréal and so far, Ted appears to be standing all by himself.

Where are all the other folks that shot down this idea earlier? :)

Thanks,
Tom
