The De-Evolution of UX Design

Proper IA/wireframing/signing-off-on-steps is good for companies where a clueless management is going to make myriad changes to information hierarchy or UI bits along the way, because you have a "we talked about this already and you agreed" defense when some clueless marketing guy comes over and says things need to be bigger, this link needs to be here because it's his friend's company, etc.
A lot of what this article is proposing is missing (organizational hierarchy, an understanding of the order of information) is something that I don't really think is missing in a good tech-company designer's head. He or she is often one of few in control of that domain, and the product roadmap is often known quite a bit in advance. A lot of the polar bear book's 1000+ pages ends up getting turned into heuristics, when quick decisions and fast iteration under multivariate testing is often better off for a young company than sitting back and doing some type of holistic, IDEO-class set of mental exercises.
I would agree that a lot of the stuff that is missing can be in a good tech-company designer's head! Totally with that.
But can we say there's really a "devolution"? Is there not progress in not following Morville and Garrett to the letter? I find a lot of dogma in "UX" practices that make designers feel comfortable, and I just as often find many UX designers to overstate their impact on things because it is not as easily quantifiable as an engineer's impact.
For projects measured in manyears instead of manweeks or months, a solid IA is essential.
Seen it done right and disastrously wrong (e.g. when a large Global 100 Player tried to create an IA across all their suppliers & companies).
