Agreed - It's beyond wrong. For example, at the core of plenty of numerical libraries is 30+ year old fortran code from netlib that works great. It's just done. It does what it's supposed to. It does not have meaningful bugs. There is no reason to change it. Obviously, one can (and people do) rewrite it in another language to avoid having to have a fortran compiler around, or because they want to make some other tradeoff (usually performance). But it's otherwise done. There is no need to make new releases of the code. It does what it is supposed to do. That's what you want out of libraries past a certain point - not new features, you just want them to do what you want and not break you.
