I think this would be a great topic of discussion and allow different points of view to share their thoughts and see if we can remain civil and engaging! My challenge to all!
Let me begin with my short overview opinion:
Traversing is a good skill to have! Being able to traverse well requires a functional body position in which one turn can be ended into and another can be initiated from. Using a traverse as an exercise can hone a good body position and highlight deficiencies in the same. Having a solid traverse is a vital skill to expert skiing.
Traversing, as a habit, disrupts rhythmical, fluid turning. Traversing is a problematic method used by less skilled defensive skiers who's intent to turn is to stop going there. It leads to "shopping for turns" and kills any chance of fluidity and rhythm.
