So, we've resolved this particular API in question 
(css.document.MediaDescriptor) since that one was, although marked 
'published', practically equivalent of being unpublished.

But I still have concerns in this area.  What if we discover an API that 
should be (or should've been) unpublished way after the initial 4.0 
release?  This may happen as we venture into areas where nobody has 
really ventured into up until now, and discover some obscure use of 
"published" API which hinders further rework unless the API is 
unpublished.  Since we still have lots of areas in our code base where 
nobody has stepped up to claim maintainer-ship, this is a very likely 
possibility.
