"libglvnd" is in "use.force":

# Force USE=libglvnd in order to mask app-eselect/eselect-opengl for removal.
# This USE flag will be removed completely in the near future. Bug #728286
libglvnd
# Mike Gilbert <flop...@gentoo.org> (2019-07-20)
# Disabling this requires a migration to be performed.

# Force the GNU/Linux ELIBC, KERNEL, and USERLAND

======================
For the rationale behind prefering libglvnd over the eselect-opengl hack
(which has caused me more problems than it solved, even on single-GPU
systems), please see Ashley Dixon's reply.
