As I said before, I think there will be a last-minute reprieve for the IMCR, using some political fudge to save EASA's face on "total European standardisation".
I am sure the UK CAA will support this.
They have said so (I went to that 1/08 CAA/EASA presentation and made copious notes) and it would make sense too, because they know damn well that all that a removal of the IMCR would do is stop UK holders
overtly asking for the approach...... a bit like I can't overtly ask for a GPS approach because my IFR GPS is not approach certified (it fully works but I don't have the POH supplement with the proper wording) but I could sure as hell fly the same track (especially if it is all in Class G

).
So you will have traffic flying the IAP/ILS
non-radio, (well, they will make a "long final" call, as they are "VFR"

) which is probably OK (as they say, when god made the sky he made plenty of it) but it is going to make some high up people awfully nervous, especially when they get a TCAS warning
Also, aviation has a decades-old precedent, worldwide I am sure, for never stripping any pilot of privileges. Stuff always gets grandfathered - sometimes with a generosity that defies any logic or the subject's actual training record.
The CAA have been tight bastards (especially in their medical department) in holding up a high bar to the initial entry into flying, but once you got "in" they have always bent over backwards to keep you in.
