I don’t think having the DoH server also present blocking information is a good 
idea. The draft does also not put any restrictions on the URI template and I 
would rather have my DoH servers focus on delivering DNS answers via DoH.

So I think a registry is needed. What that registry is and who will be in that 
registry needs to be discussed. While the definition in 6.2 does not put any 
limit on that the last paragraph of the introduction does. A better way to 
limit that IMHO would be to allow only resolver operators to be added to the 
registries that are under regulation as only those are usually forced to block 
stuff and hence need the transperency.

That is what draft-ietf-dnsop-structured-dns-error says in section 5.3 anyway, 
and this is an extension of this as I understand it.
