I would expect someone throwing that title around to have rewritten most parts of the stack themselves, in several languages; to figure things out or to custom build something that needs a tight fit. That kind of general purpose capability; to jump in wherever and solve whatever problems; means tens of years of focused thinking and coding for most people. To me it's very much about being a potential leader/mentor, official or not; and duct taping what's hot today into working solutions is not the kind of experience needed to guide and teach; not enough perspective. I feel so old writing this, we lost something priceless along the way to awesome profits.
