Anyhow, your concept of "craft" is largely debatable, the evolution of composition, in a constant way, has been to loosen the framework, the rules, the canons of structure, harmony, counterpoint etc.
In the end of the day, a musical work is appreciated or despised according to subjective, emotional reactions, and not through objective, technical criteria. So it's not even a debate on "style" it's a debate on "taste". Composers aim at striking an audience, not a small milieu of universities and competition juries.
Let's not forget that Bach in his time was considered a second rank composer by his peers and by the public. Because his music did not match the concept of a composer's "craft" which was valid in his time.
