Personally, I would not take this into consideration when deciding how much to pay people. I recognize that there are a lot of different niches in our industry, and presumably in some of those niches this narrow focus on what technology is being used makes sense, but that hasn't been my experience. In my experience, you want people who are both pragmatic and flexible about learning, evaluating, choosing, and teaching others new tools. I do recognize this may be a somewhat privileged view. I think I've been fortunate to spend my career in organizations where software is the profit center rather than a cost center supporting the rest of the business. My experience is that these companies have focused their hiring, compensation, and performance expectations on fundamentals and figure-it-out-itude rather than any specific technology stack.
