echo "You must be root to run this."
Below: is this my PEBKAM, or (with a system that is preconfigured to
deny login as root) _should_ there be an echo of the requirement to run
as root?

Sudo means that you are root. *LOCKED* just disables the root password.

Thanks for the clarification.

As background: I spent many hours repeatedly testing freebsd-update
upgrade from 12.1-RELEASE to 12.2-RELEASE-p3 (and greater) in virtual
machines, trying to understand why (a bug) mysql57-server would not
install following an upgrade with the root password _disabled_.
Later tests included multiple consecutive successes (bug-free) with the
root password _enabled_ – enough consecutive successes for me to assume
that the bug was somehow caused by the *LOCKED* aspect.
That period of consistent success was followed by reproduction of the
bug with the root password _enabled_, at which point I realised the
wrongness of my assumption. Confused by the randomness, I began to
wonder whether – in rare situations – sudo might be not entirely effective.
Eventually I realised, the failures to install mysql57-server were
symptomatic of FreeBSD bug 232921
<https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=232921>, which
involves pwd_mkdb(8).
I'll not attempt to understand why bug 232921 was not consistently
reproducible during my tests, but I'm glad that it's unrelated to
disabling the root password; and I no longer doubt the usefulness of
sudo :-)
