I would much prefer a Standards-Track document that says to
authenticate the origin domainname as follows:

 - use DNSSEC for all DNS queries needed to find the URI RRs and DANE
to authenticate the authorities of the resulting URIs

or

 - expect the target authorities to have certificates that
authenticate the origin, using SNI if need be.

I would still drop everything related to NAPTR and DDDS.
