Worth adopting by who? I once replaced a convoluted pricerule framework based on fixed options in a booking system with a simple evaluator that exposed variables for number of days, number of guests etc. That was very much worth adopting for that specific use case. Your line of arguing always assumes that any solution has to cover all bases, which is just not true when you're solving a specific problem. And no, the same doesn't apply for everything in technology. The continuum for operating systems starts at a much higher level of effort and cost of maintenance. Nothing is black or white.
