In the meantime, the IMCR is a fantastic privilege which every serious pilot should get and which gives him similar rights to the full IR - except no Class A, min 1800m vis, IFR in UK only.
Similar rights but in the vast majority of cases not similar training or experience and that is where the problem lies in the eyes of our regulators.
As I said before in my opinion the correct way to go around this is to separate the IMC and the IR, stop making inferences that apart from Class A they are interchangeable and drive home the fact that the IMC is a safety and skill enhancer for the private pilot.
Leave the politics of changing the IR to follow it's natural course, which is something that some of us have been working on for a number of years now and know better than IO's guess about the way the wheels are turning. It is a slow process but one that is happening.
