I guess some kind of fundamental difference makes it not that simple.

I don't think any current display hardware uses planar graphics
hardware, so it's possible that it would be harder to support under
modern X11 (it's been a decade or so since I last looked at any X11
code, and that was not a particularly deep look at the time).

netbsd-9 builds of the WSCONS kernel (from nyftp.netbsd.org) include
it from a day or so ago, and it will be in NetBSD 9.3 and 10.0

It would be an interesting project to try to build a kernel which can
provide the ite interfaces used by the X11R6 x11 drivers as well as
WSCONS. That would allow the GENERIC kernel to use wscons (for all the
console styling benefits and Xwsfb usage), while still allowing X11R6
X binaries to continue to run. Of course the real challange after that
would be to look to port one or more of the X11R6 X servers to modern
Xorg :-p
