The IMCR is well worth doing even just for the skills - even if one got zero legal privileges for it.
A typical UK summer day is hazy, and if you are down to 3000-5000m viz that is practically IMC (unless you are flying really low e.g. below 1000ft, and you know the area) and there is no horizon. You are legally VFR on a plain PPL, but you need instrument skills to fly in that.
Plus radio nav is a super capability which transforms the confidence to go places. No more looking for villages, railways, dual carriageways, Nokia factories...
It gives you IFR privileges for UK for Class D-G, and VFR VMC on top privileges worldwide.
The IMCR has 4 years to run but I would bet there will be a solution at the end, most likely in the form of some kind of "EASA IR" with an intermediate module which gives some IMC privileges.
