This is not generally true. It strongly depends on whether they use
modular Xorg or not. The existence of /usr/lib/X11 doesn't orivide
anything useful at all, given that older FHS recommented those to always
exist or provide a symlink to /usr/X11R6.

It is not common sense. You will run into random issues with various
problems here anyway. Ultimately, /usr/lib64 shouldn't have to be added
explicitly at all, but I guess they fucked up too much for that to work.
