Instead of returning null when a performance counter has not been installed could we please return a null implementation. This way the performance counter information would simply be swallowed if it has not been installed yet.

I agree with this, but in my application I use to create my own specialized interfaces around an helper, and create those null implementation over my interface, because I think an helper should be an infrastructure component, and don't make this kind of choose for you.
