Folks,
This is a rather specific point that is probably worth having the
DT work on, offline.
Offhand, I think this describes a solution that is, at best
cumbersome. Unfortunately the scenario it is trying to solve is
a reasonable -- and probably even a probable -- one.
Thoughts?

I've been talking about implementing CSV with my

properly you must have positive CSA records for all your

PLUS a wildcard negative CSA record.
The CSV design did not intend for negative CSA records to be
common. If you do need to discourage the use of wildcard
subdomains, you'd do better to use wildcard DNA PTR records
(suggesting an accreditation service which will report "don't
trust these folks").
