So why are you insisting on incorporating a bit of design that ensures
that people can't use dozens of existing applications for working with
VP8?

If you want to have an application that does something bizarre with
the alt ref, that application can special-case it.  It'll work even if
you use a packed B-frames-style trick as Michael proposed: none of
this stops you from having that flexibility if you really want it.
What it does do is keep backwards compatibility with the rest of the
world at no cost whatsoever.
