Well, then you could probably load up Lomac, which is far more realistic when it comes to air-to-air than SimCopter comes to realistic SAR. This is just a silly argument.
Just think of the new dimension it would add to DCS if you can be a combat chopper pilot doing troop insertions, rescue operations, recognizance missions, etc.
I believe many people in this forum enjoys AVIATION as much as blowing up things. And CSAR missions needs much more piloting skills in terms of FLYING than standard CAS missions.
