I just tried it. I removed bluez, which took out bluetooth, and left
the configuration files for bluez. It also listed nine packages that
are now ripe for autoremoval.
I then ran apt purge and it merely repeated the list of nine
packages. The bluez configuration files were still present.

You wrote:
"I expect that, by context, running
apt purge
without the restriction specifying particular package, will apply
apt purge
to all installed packages, according to what purge does, in relation to
packages."
which is as clear as mud to this English speaker. It would be easily
interpreted as:
apt purge <list of all packages on the system>
Cheers,
