Even if it didn't break block eselect-opengl with mesa, it is generally
extraneous for most non-NVIDIA users. From [1]:
libglvnd is a vendor-neutral dispatch layer for arbitrating OpenGL API
calls between multiple vendors. It allows multiple drivers from
different vendors to coexist on the same filesystem, and determines
which vendor to dispatch each API call to at runtime.
See bug [2] and commit [3] for details regarding the breakages in X for
modern-NVIDIA users without libglvnd.
(Video drivers do not actually require an X server to be present, as unless the
`nomodesetting` parameter is given to the kernel, they can be initialised pre-X
to provide high-resolution TTYs.)
