Recent snapshot versions of setup.exe have a dependency checker that
will give you a list of any broken dependencies.  Using this you could
deselect the X libs, press Next, and it would show you a list of "pango:
required by lilypond ; xorg-x11-bin-dlls: required by pango" and so on. 
It's slightly better than having to read setup.ini manually but still
perhaps not as intuitive as it could be.

Yes indeed, uninstalling X11 is currently quite an annoying task to do
with setup.  There should definitely be a way to make this easier but
SHTDI.
