I agree, but I still think this draft represents a good approach, and we
should adopt it.

In my view, the WG has been stuck trying to choose between principled
long-term solutions that will take many years to implement, and ugly hacks
that can be deployed quickly.  In fact, I think we should develop both.
This draft is the former, and if we adopt it, we can and should follow with
interim solutions that can "upgrade gracefully" over time.

Adopting this draft, even if we are far from implementation, is important.
To choose good intermediate steps, we first need to know what the endpoint
looks like.  For example, with this draft in place, we could define a flag
in the DS record meaning "use encrypted DNS like in ADoX", with resolvers
querying for the SVCB record in the child if it isn't provided as glue from
the parent.
