even if it's meant as a joke, I must point out that the opposite is the case 
here: it will horribly fail on Wayland if it assumes a $DISPLAY!

Also I must point out that there are horrible interaction problems on the X11 
platform. KWin does not get enough information to prevent focus stealing 
prevention from kicking in and thus the dialogs do not get focus. This problem 
(to my knowledge) does not appear with kdesu. Thus I would consider switching 
all kdesu to polkit as a regression. This is a long standing issue which must 
be fixed by polkit and hasn't been addressed in years although the problem and 
how to solve had been explained by the current and previous KWin maintainer.

This problem is not unique to polkit, to be fair. We see the same problem with 
akonadi asking for passwords and also with the GPG ask dialog.

Cheers
Martin
