The main difference between having a straight PPL and an IMC is that next time that GD found himself in this situation he would have more arrows to his bow.
Climbing into safety (albeit in IMC) would be one.
If you are going for an IMC rating make sure that your instructor knows what he/she is talking about so that they can teach you beyond the basics.
More emphasis should be on en-route and cockpit management than most people experience.
