Raising the nose too early on the other forms of take-off will increase aerodynamic drag at a point where the aircraft is not able to fly yet and will consume more runway then necessary.
You have to raise it pretty high to get a substantial drag penalty. In the POH for my tail dragger the recommended technique is to take off from the three point attitude. It may be marginally shorter raising the tail in the takeoff run but not much. The three point attitude is very close to the stall. IMHO raising the tail in this aircraft is a better technique than the POH recommendation.
