Pace is getting to a valid point - the IMC rating is not wholly about flying under instrument conditions, it is about offering an ADDITIONAL level of pilot training that can take a pilot to an enhanced level of flying skills and can add to the safety of his/her flying by the ability to use instrumentation. I see no reason why the training and the qualification should not continue for this sake alone even if there was no official 'out of sight' privileges gained. In my case I never flew in instrument conditions but the IMC training, post PPL, made my flying better, more precise and more enjoyable.
