That sounds like a good idea, but please start a new thread (not reply to
some random existing ones), with maintainers for drivers/gpu/drm/vmwgfx
only. Not a massive list of random folks who have no idea what's going on
here. From get_maintainers.pl

$ scripts/get_maintainer.pl -f drivers/gpu/drm/vmwgfx/
VMware Graphics <linux-graphics-maintainer@vmware.com> (supporter:DRM DRIVER FOR VMWARE VIRTUAL GPU)
