I tried the options when I tried systemd-run, but it didn't work.
I only added them, but now I see that you have to choose: or them or 
setpriv.

Now it's:

systemd-run --unit=kaffeine-resumed --uid="$kafuid" --gid="$kafgid" \
      env XDG_RUNTIME_DIR=/run/user/"$kafuid" $kafdis 
XDG_CURRENT_DESKTOP=KDE \
      /usr/bin/kaffeine --lastchannel > /dev/null 2>&1

Outcome is the same.

The only difference is that a line is added to syslog about unit creation:
Started kaffeine-resumed.service - /usr/bin/env 
XDG_RUNTIME_DIR=/run/user/1000 DISPLAY=:0 XDG_CURRENT_DESKTOP=KDE 
/usr/bin/kaffeine --lastchannel.
