ACK. I really wish the xfce4-pulseaudio-plugin dependency were
downgraded to a Recommends:. Note to self, submit a bugreport!

While I agree that marking all dependencies of xfce4 is a PITA, the list
is not all that long. Even if it were
sudo apt-mark manual \
$(dpkg-query -W -f '${Depends}\n' xfce4
| sed 's/([^)]*)//g; s/,//g')
should do the trick.
Warning: Check the output of the command in $() before feeding it to
apt-mark. If there's any `|` in there, DON'T feed it to apt-mark.
After that you can, in theory,
apt purge xfce4-pulseaudio-plugin
without losing your xfce4 dependencies.
URK! Dogfooding this, I am told that another 150+ are going to be
purged, most likely because of task-desktop and task-xfce-desktop being
automatically installed.
Hmm, doesn't look as easy as I first thought.
Oh well, perhaps this helped. If not, too bad.
