Thanks for improving the clarity of this draft.

Could you provide an example of a use case where the baseline DOH behavior
is not sufficient, to motivate the "proto" parameter?  The text mentions a
"transparency principle" as motivation, but I don't understand the
significance of this principle.

In particular, I think the draft should explain why it's not sufficient to
apply truncation when the proxy packages an HTTP DOH response into a DNS
response over UDP.
