And you base that statement on what legal theory?

This isn't a patent issue (that anyone's aware of, anyway), nor copyright,
license, or trademark.  It may touch on trade secrets, but that's explicitly
permitted in cases of promoting interoperability.  Which leaves us with...?

FWIW, I'm perfectly fine with whatever Mark wants to do.  64 isn't a major
win for anything but marketing, and if only one application really needs
that support for compatibility reasons, then maybe the best place to add
the relevant routine is in the application itself.
