To be fair to the CAA, they are right to keep silent on this intensely political stuff.
France has the advantage of being French i.e. they are very polite in the open and when the door closes they stick their middle finger up and do as they please. This is an effective way of dealing with the crooked gravy train riders who are in charge of the EU, but the UK CAA doesn't have the balls to do stuff which is quite so crude.
I am sure a way will be found to preserve the IMCR, but you won't hear about it till the last minute. So much s**t has hit the fan over the EASA proposals to shaft IMCR and FAA IR holders that EASA had to do under the table deals with MEPs to get enough votes, and the under the table stuff would have been assurances that such and such will be solved amicably.
