Hiya,

Could well be my terminology was imprecise. What I recalled
from some discussion a year or more ago was that RPZ MUST NOT
change a DNSSEC-signed answer that verifies.

If that's wrong or no longer the case then my point there is
off base. (I'll go back and find another tomorrow:-)

If I'm correct, then I remain puzzled as to why Paul V. finds
it acceptable to be unable to "interfere" with DNS answers in
one case (RPZ-with-good-DNSSEC) but not the other (DoH).

Cheers,
S.
