No, as I said, there seems to be no systemctl command that will remove
or add the user "template" links.  The commands you gave are for links
under ~/.config/systemd/user which are local to each user.  The
template links under /etc/systemd/user are applied to all users when
they are first started and a user mode systemd executable is run for
them.

Yes, it appears that is the way I disabled it in 18.04.  I have just
checked my /etc/pulse/client.conf file and it has been edited to have
"autospawn=no".  But in 20.04, pulseaudio was running again, so it
must be ignoring that option now, or how it works has changed.

Yes, in XFCE4 that is in Settings > Session and Startup >
Application Autostart as I mentioned.  With the service disabled, I
suspect that this option might well have started pulseaudio, so I
disabled it there too.  With pulseaudio already running courtesy of
the user systemd instance, I expect that the Application Autostart
option (if enabled) will start another copy of pulseaudio which will
see that the original copy is running and shut itself down again.  But
I have not tested that.
