Definitely agree with that thinking. I'm just hoping that eventually
the file be /etc/X11/xorg.conf.d/synaptics.conf or such.

I'd say leave the x11_options stuff in there for now since you already
have the code and there will be no other way to configure the devices.
If my patches land, we can always strip that part out. There's time
