I think there are different classes of applications, - some that don't really need any time spent on design at all, and some that absolutely do - and for a while the former class of applications became predominant (possibly because of the rise of quality middleware and frameworks that did the heavy lifting ), and the methodologies became mainstream, and adopted universally. Hard to generalise beyond that.
