Yeah, but AIUI one of the points of the recent buffer display reform is
to provide a unified customization interface, so I think it would be a
shame to still leave cases which the user has to handle outside of it
(which in this case would be particularly ugly, as `quit-window' doesn't
seem to provide any means to hook into what it does other than the
prefix argument).

Perhaps `quit-window' could check if a relevant specification exists,
and default to the current behaviour if none is found?
