Given that the PEP currently explicitly supports ur, I think the
reversal of the reversal will need some discussion in the PEP.

(this reminds me of Germany's path wrt. nuclear power - where the
previous government decided to pullout from nuclear power (der
Ausstieg), the current government reverted that (Ausstieg vom Ausstieg),
and then, after the Fukushima accident, decided to revert that decision
(der Ausstieg vom Ausstieg vom Ausstieg aus der Atomenergie)).
