Hi Martine, all,
FWIW:
With regards to [1], and given that DNR was explicitly mentioned, please note
that the DNR version in the RFC Editor queue says:
The "alpn" SvcParam may not be required in contexts
such as a variant of DNS over CoAP where messages are encrypted
using Object Security for Constrained RESTful Environments
(OSCORE) [RFC8613].
Also, Ben made a similar change to accommodate non-alpn cases:
https://github.com/ietf-wg-add/draft-ietf-add-svcb-dns/commit/65927be7ba79fbc6c93a2c793f8b8b455b394ea5.
I don't think this change made it to public version though.
Cheers,
Med
