Very low hour PPL in general and even much more low-houred in taildraggers, but doesn't a wheel landing in a crosswind just postpone the problem? I can see why tail up with unobstructed rudder and higher speed would give better control at touchdown, but one has to slow down and get the tail down at some moment, and if I remember my TW instructor correctly, that results in an even more vulnerable moment compared to putting two wheels (windward main wheel and tailwheel) on the ground, especially with a steerable tailwheel (as in the Citabria I had my few lessons in).
