On the contrary I think the discussion is helping to identify these
issues and where they figure in the overall scheme of things. The
three contexts you mention are inter-related. What's in or out of one
of them will have some impact the others.

Indeed. But this means some minimal standards/requirements for those
trials that do involve DNSSEC so they can interoperate. And there
needs to be some convention for handling the interactions between
DNSSEC-aware and non-DNSSEC-aware entities. [ie If an application
expects a signed answer from the DNS and doesn't get that, what should
it do?] These are reasonable things for this ETSI document to cover:
not that I have any say on that of course since my employer is not an
ETSI member. Another topic the ETSI document could/should look at is
IPv6 interoperability: what if a name server or registry/registrar for
ENUM was IPv6 only?

As far as I can tell, nobody is disagreeing with this. However ENUM
trials should look at as many aspects of a production ENUM service as
possible. DNSSEC is just one of those things. As is IPv6. And
EPP. And....
