Politics is about the art of the possible. A Euro wide IMCr maybe impossible.
Politics is also about keeping the rabble happy. There will be a lot of UK pilots who have spent £4K or more on an IMCr who will be pretty annoyed if they cant use the rating, the more so those that read the words of EASA / CAA when they briefed the press in London two years ago. EASA could have got away with this one (if they wanted) if there was a safety case for abolishing the IMCr - but there isnt.
It is going to be very interesting to see what they conjure.
