I find myself agreeing with SkyRabbit, Twin Aisle and Trodden masses here.
Bose-x I understand your viewpoint but am afraid i can not concur with you.
Although we are unable to ask people under what license they are flying it becomes blatantly obvious when conditions deteriorate who is flying under an IMC rating and who is on an IR rating, the lack of confidence can become quite apparent. That is not to say that those flying with an IMC lack skills , far from it they are pilots who have committed time and expense to their hobby,but that is what it is to the majority of them simply a hobby. Those with IR ratings in the main have them as they wish to or either already do so fly commercially.
I see what you say about practice and experience and there will always be those who buck the trend, but the IMC rating was never designed as anything other than a " get me out of this" rating ideally suited to the British Climate and the tendency for the weather to rapidly change
