"ANAME and its proprietary friends try to solve the issue it within the DNS"

Matthijs sums this wonderfully.  As a Chair, I would say ANAME is using DNS
to solve a DNS problem.
I felt Tony did an admirable job trying to simplify the current draft, but
it does seem like it's still too much.
The current draft covers Zone Transfers and DNSSEC, two issues which the WG
signaled out as
being crucial.  It is also a solution which works for whatever technology
replaces browsers.

As a chair, I stepped back and let the working group has this out as DNSOP
does best.  T

I've been happy to see the engagement on the svcb draft, as well as the
browser community.  The chairs
have felt that level of engagement was important for us to move svcb
forward.

Neither solution fully replaces the other, which makes a working group vote
of "A vs B" as not so simple.
