Indeed, dogmatic adherence to arbitrary patterns is a huge problem in our field. People have strong beliefs, "X good" or "X bad", with almost no idea of what X even is, what the alternatives are, why X was something people did or did not like, etc.
What you think is usually the limit of your experience, which effectively makes it anecdata. I've looked at enough companies and dealt with the aftermath of enough such instances that I beg to differ. It's possible that due to the nature of my business my experience is skewed in the other direction which makes that anecdata as well. But it is probably more important than you think (and less important than I think).
