No matter how easy or difficult your license is. At the end of the day, you will be the one flying with it. I seriously doubt that the minimum requirements set for an FAA instrument rating make you safe flying in all weather ops.
I was line training a new F/O a while ago in a 737, and he got itchy descending through an altostratus cloud layer on autopilot. No joke.
Seriously want to see him operating single pilot IFR in a Caravan.
