Joe Sixpack clicks through today. He will, too, later, but, one of
the Fine Things with DANE is that no entity can produce valid data for
anything outside its own domain(s). Damage limitation is quite important,
while admittingly not being the silver bullet.

The existence of a free and secure chain of trust will put a price
pressure on DV certificates, which just might create a situation where
the marginal cost for doing TLS is so low that it is hard to set up a
web site without.

Taken together, this creates a situation where valid, verified
certificates are the norm, for real, which makes it all the more possible
to flag the exceptions much more annoyingly. Perhaps even refuse to
open them.
