???  Necessity no.  Are there practical benefits yes.

The policy of the kernel developers in general is that if your apps
includes kernel headers and it breaks, it is a kernel problem.

As for ioctl it is a giant mess that needs to be taken out and shot.

And yes there are places where even the mighty glibc is in the wrong.
