Engineers realized that maintaining all those bug fixes was too expensive. So as an industry we collectively agreed everyone will do constant rewrites. That win 95 fix? Doesn't matter because win 95 was auto upgraded to be unrecognizable (SaaS is a wonderful thing). Low memory? Not our problem - go buy another computer. Remember programmer time is more valuable. You can try and buck the trend but your dependencies wont and the customer doesn't care whose code the bug is in. You won't get any browny points so you might as well just save the effort. It's a brave new world.
