Because it isn't a thing that a free software community can do
collaboratively in the open and involves requiring proprietary software.
Maybe a third party could do it for their own binary builds, but I don't
see how we as a community can recommend it, nor would I want to
recommend it myself.

:) Since the JCK is under NDA that claim is not verifiable. But you
could say that the JCK assumes one particular interpretation yeah.
Still, if a secret test suite would say things should work one way, but
actual programs expect things differently I would go with not breaking
existing stuff.
