Sometimes those historically best practices become outdated but clung onto as doctrine by programmers who let experience get in the way of evolution. What may have been true 10 years ago may no longer be accurate or important but is still held up as a best practice today. If allowed to evolve then we are all good but finding the correct speed of evolution (and helping everyone evolve at a similar speed) is harder than ideal. Flip-side of that is the organization or programmer that blindly chases the new.
