    You raise some interesting questions. However, note that the purpose of CGJ
    is intended for sorting related distinctions, which are at issue here. This
    is different from variation selectors which are intended to be used for
    displayed variations.

    Since sorting is *language* specific and needs language specific sorting
    tables, the use of CGJ is also *language* specific.

    Therefore, the combinations for which CGJ would be used in the type of
    bibliographic records are a small an fixed set. For display, CGJ is
    supposed to be ignored.

    Furthermore, the distinction between umlaut and is not something that's
    generally carried, but limited to specialized data such as bibliographic

    All these factors need to be taken into account when comparing this to a
    general solution that's *script* specific and is not limited in its domain
    of application. You might find that some of the concerns raised in the
    context of the other discussion no longer apply.
