    I know... this is kind of an informal advance proposal, intended to lead to
    the UTC doing exactly that.

    Though there is a second question of whether the Variation Selectors, or a new
    block of differentiators, could be opened up for use as a "PUA for each
    codepoint". This could allow user communities to set up auxilliary unofficial
    standards (such as my Archaic Greek alphabets), if Unicode chose not to take
    the effort in that regard. There would be some other benefits in preventing
    PUA conflicts as well, whether user-community-standardized, or left to
    individual font use.
