That's the same as my second case.

"rooted FQDN" is also not well-defined outside this thread. I don't =
think just adopting the terminology unilaterally is going to make it so.

The dot doesn't specify the name of the root. That's why it's confusing.

There is no null label string following the dot in a fully-qualified =
domain name, in this context. You're confusing the presentation of =
domain names with wire-format encoding of domain names.
