Hi Bill Actually airspeed must be increased in a sideslip because stall speed is raised also. This is because the wing becomes less efficient and the lift drag ratio is reduced. This means a greater angle of attack (nearer to the stall) at a given airspeed to maintain lift or alternatively you must increase air speed. If side slipping an approach you should always be applying some forward stick at the same time hence the steeper descent angle. Flaps were invented to overcome this as you say, to give a steeper approach angle and reduced airspeed. Side slip without forward stick has killed many a Tiger Moth pilot since it can put you into an opposite spin with no altitude in which to recover. Aerobatic pilots actually use this to advantage ti initiate spins at safe altitudes.
Also an approach in a cross wind is a crabbed approach not necessarily a side slip. The aircaft should still be balanced relative to the wind (ball central) but its approach relative to the ground is skewed. In a side slip the ball is one way or the other depending on your rudder input and this can be achieved without cross wind if desired.
