This is correct.  It should have been done during X11's Beta - I wrote
much of the code but never got time to finish it.

A paper by David Lemke and myself on this topic has been accepted for the
San Diego Usenix.  The fact that the problem is interesting enough to
get a Usenix paper out of should tell you something :-<

Many X servers will have multiple visuals.  Some (including the X/NeWS
server on color displays) already do.  Many,  maybe most,  color X applications
I have seen do not work correctly in these environments.  This was the
observation that led David and I to write the paper.
