There is a whole pile of wisdom contained in these past few posts, very interesting responses and I'm pleased to see that there seems to be a concensus to keep things as they are.
Nigel, the military IFR capability in the Gazelle/Scout was/is just that - a capability. It was not something used in anger on a daily basis but the pilots were well trained and always current, therefore, if IFR was required and the weather was suitable, it could be done. But be under no misapprehension, to maintain that capability takes quite a bit of effort and the whole issue of instrument flying has to be taken very seriously and closely supervised by a proven chain of command. I do not believe this is where we ought to be going with single engine helicopters in the commercial/private world.
