Didn't think of it.  It might work surprisingly well, but I don't find
it very attractive.  Instead, I was thinking of something more like an
explicitly specified (partial?) ordering.
E.g. Ediff could have somewhere

  (define-display-buffer-class 'ediff
    'ediff-a 'ediff-b 'ediff-ancestor 'ediff-control)

Or maybe such symbols could simply be predicates (simpler to implement
and more general).
