I am also not eager to see additional bug reports for this case that
will need to be fixed under the precedent that we accepted a patch to
fix it before.  If there's a concern that rejecting these hostnames
altogether would break existing users, then we can just do nothing, and
tell users that their syntax is not valid and they need to fix their
hostnames.  This rule has been documented since before ISO standardized
C, so it shouldn't be new to anyone deploying systems or DNS.

So I'm fine with doing nothing, or rejecting these hostnames, but not
allowing more lenient syntax, because it will probably be broken
somewhere and we (or someone else in the ecosystem) will have to deal
with it again down the line.

FWIW, I'm fine with doing nothing. But it will still come back further
down the line, because it _does_ work most of the way, and has for a
long time.
