The general idea of the patch is right, the implementation looks OK as
well, but I have one major issue with it: why do we ever need to know
the "version" of the window-system?

I've only ever seen it used to display diagnostic data, i.e. to
help debug some problem, but I've never found it useful when debugging.

IOW, I'd much rather mark window-system-version as obsolete.
