I remember seeing something go by during an upgrade somewhat recently
about there now being a defaults file that gets used when a user does
not specify a .vimrc.  Unfortunately, I don't remember whether I saw
that notice on a FreeBSD machine or a Debian one, and haven't been able
to find the notice I remember through searching some likely places.

Just to check: do you have a .vimrc file in place already?
