The 90% of Xvfb code that's shared with Xorg is well maintained, the Xvfb
ddx layer itself doesn't get that much attention. As for Xvnc, it depends
on which Xvnc you use - RealVNC's is basically unmaintained now, but TigerVNC
seems to be doing well for a new project, and TightVNC & TurboVNC are still
alive as well.

Unfortunately, choosing which modules to load is restricted to root, since
Xorg is setuid root, so a admin would have to set it up for them.
