+1. We should not be in the business of documenting or declaring our
intention of having vaporware. Say we get a patch and for some reason it
gets rejected. We've had features that took two or three releases to get
accepted. This is why we've historically shied away from roadmaps. And
we've been bitten in the past by deprecating things only to undeprecate
them later.
