Disregarding the regulatory considerations, it has been stated on this forum many times that the skill set provided by good IMC training (and maintained through including IMC sorties with your VMC flying) is something that cannot be taken away from you. It enables you to deal with the obvious - entry (inadvertent or not) into cloud - as well as those conditions where although the conditions are technically VMC, instrument skills give you comfort: water crossings with no apparent horizon, hazy days where the VV is fine but horizontal visibility is terrible.
It's a fun course. Go for it. The ground exam is not difficult (but many people prefer to study beyond the requirements for the theory exam - Air Pilot's Manual Vol. 5 is good for learning about holds etc. that are not required for the IMC skills test).
