That can be argued, but they're pretty esoteric. For example, what language are they written in? Fortran, assembly, etc.? Probably nothing the majority of developers or mathematicians can't understand. And creating bindings for them is non-trivial. I don't even know where to start from the website. And on the website, all the links to the routines are broken. https://www.netlib.org/blas/
The naming convention is a bit esoteric, but once you figure it out it's not too bad. I don't think writing bindings is too hard once you know what's going on. You most likely would want to write some kind of wrapper on top of that in order to make things a little more user-friend.
I will agree with you on the routines being broken. That happened within the past year. Not sure why it happened, but it's annoying. If you know the name of the routine you can usually find documentation on another site.
