They might never be finalized, and even if they are mere mortals might
never get this hardware. Merging infrastructure without any users is a
bad idea in general, and merging infrastructure with no user that
exposes untestable user interface and bloats core data structures is
even worse. I don't think this has any merit at all at this point.
