Oh, this is true, and I should have been clearer. IDSs as a way of *representing* unencoded characters is fine. It’s what they were invented for. And any rendering engine that can turn these into visually-pleasing glyphs is welcome to do so (see TUS pp. 750–751).

IDSs are not, however, a workable alternative to *encoding* Han ideographs as singletons. Even simpler ideas that would allow some ideographs to be implicitly encoded have been rejected by IRG members.
