Definitely worth doing the IMC. I did it a few years ago and have used it a lot since. It is really useful to be able to get on top of the bad weather when there is no class A airspace to stop you. It is also a really good skill builder for general flying. But it is not an IR and you should use it carefully. I don't fly deliberately into bad weather. You also need to maintain your skills since they deteriorate quicker than you might think since we don't fly IFR all the time and it can be a shock when you suddenly need to use them. Good luck.
