Mostly, yeah. It was very broken in 8.0, and MesaLib and video-intel
updates mean I no longer need to use modular xorg with my Kaby Lake
laptop. My radeon destop runs well too. Recent changes improved the
intel tearing situation. I'm reasonably happy.

... but I have two problems currently, with ugly workarounds in pkgsrc
(which don't work for everything).  Neither occurs when using modular
xorg, and seem to be regressions:

* r600_dri.so (and other DRI drivers) being linked improperly. Missing
libxcb symbol errors when loading libGL with dlopen, as a lot of OpenGL
software seems inclined to do. I committed a workaround for this to SDL2
the other day, as well as etlegacy. It's still a problem with software
that uses libepoxy.

* Certain programs that use OpenGL contexts can make the X server
segfault when they exit. Reproducable by compiling retroarch with
the x11+opengl options, starting and exiting it.

maya has been helping investigate both, but we're stalled right now.
