So which Moron concluded DNAME was dead?

Excerpt from latest draft September 25, 2007, September 25, 2007

This document is an update to the original specification of DNAME in
RFC 2672 [RFC2672]. DNAME was conceived to help with the problem of
maintaining address-to-name mappings in a context of network
renumbering. With a careful set-up, a renumbering event in the
network causes no change to the authoritative server that has the
address-to-name mappings. Examples in practice are classless reverse
address space delegations and punycode alternates for domain spaces.

Other usage of DNAME lies in redirection of name spaces. For
example, a zone administrator may want subtrees of the DNS to contain
the same information. DNAME is also used for redirection of ENUM
domains to another maintaining party.

This update to DNAME does not change the wire format or the handling
of DNAME Resource Records by existing software. A new UD (Understand
DNAME) bit in the EDNS flags field can be used to signal that CNAME
synthesis is not needed. Discussion is added on problems that may be
encountered when using DNAME.
