I have seen this techie ignorance many times.

Like the county IT department being told that putting a date in the filename of the page for an annual event disenfranchises all the people who have bookmarked the webpage. Yet 10 years on they still insist that their neat & tidiness (of thinking) is the most effective methodology. In the real word it ain't automatically true. When the shortcomings are pointed-out it is hubris below intelligence to ignore such warnings. But they is the experts! Yea, right!

"no further than nose" seems to spring to mind!
