"`.pidar` is not a delegated top-level domain today, but it could become
one" fired on every private name anybody has ever picked, which is every
network without a dot in its name. A warning that is always there is a
warning about nothing, and it teaches people to skim past the ones that
mean something — there were two of them in one report, side by side with
the real checks.
What is left is the collision that exists: a name that really is a public
top-level domain, which does make every public name under it unreachable
from that host, and `.local`, which belongs to multicast DNS. A name that
shadows nothing is said nothing about.
