    It is because there are problems with using 0321 and 0322 productively
    that make it a bad idea in general. Use of 0321 and 0322, along with
    overlays, should be considered not best practice. (I wouldn't object to
    deprecation, but the users of the source standards whence these beasts
    came might have objections.)

    The name "heng" was used because that is a name that has been used in
    literature for a while now. (Cf. Pullum & Ladusaw.) I'm not sure it
    would be appropriate to consider it a glyph variant of F222. I didn't
    get as much documentation on Judeo-Tat orthographies as I would have
    liked, and so the relationship to F222 in those orthographies is still
    unclear to me. But this character has recently appeared in a proposal
    from China submitted to WG2, for usage in phonetic transcription.
