Building a technical spec is not enough, indeed.  DANE hasn't succeeded
yet, and neither has DNSSEC.  But DANE is starting to gather steam (in
no small part due to Viktor's efforts) in the realm of SMTP.  The fact
that DANE was early for its time doesn't mean that the single root and
unyielding name constraints aren't appealing or appealing enough to make
a more serious try now.

As noted, the tooling for DNSSEC has been substantially improved in
recent years.  Implementations of DANE do exist now.  There are a number
of missing elements, such as a TLS extension to staple DANE that
supports authenticated denial of existence.  We're making progress
though.  It may seem slow, but there may be a preference cascade at some
point.  It may only take enough user-agent, and registrar / domain
hosting services to provide this functionality to make it popular.
