Vignatti: X Census (for 1.9)

*shrug*. Coming up with vague handwavy proposals only gets you so far when doing stuff like this, so developing the code along with the spec and releasing it when you have something workable is entirely fine, as long as you're prepared to accept the feedback, and make it known that what you've shipped may change in the future. And, just as with AIGLX, they appear to be doing this so far, so I can't really fault them.
