Yes you MUST get X wind landing instruction in a taildragger BUT the correct technique will depend on the pilot and the aircraft as well as the extent of gusts.
In relatively stable cross wind there is an argument for the three pointer. You are at minimum flying speed and minimum forward speed (not stalling it on by the way - typically you are just below critical AoA though not true in ALL cases). The argument is that you are then in contact with the ground with a cross wind for the minimum amount of time and at the slowest speed (allowing you to stop quickly).
The three pointer, by definition, requires a higher speed. You are still going to have to pass through the lowest speed condition and the wheels are in contact with the surface for a longer period of cross airflow.
In gusty conditions the wheeler means you have a lower AoA and are less likely to find yourself taking off again when a gust arrives. I would then use the wheeler in X wind only when it is also gusty.
BUT this is all type dependent. There are some aircraft which because of rudder effectiveness (lack of) with tailwheel down, and due to angle of incidence of the wing at rest, plus tailplane / elevator effectiveness, favour wheeling on.
A good instructor will let you get a feel for the aircraft you are going to fly in a number of different configurations so that you get an understanding of the limitations.
