    Spacing diacritics are not "on the edge" of the standard, when they
    are already given a full block and handled there as symbols (not as
    letters as suggested in some parts of UAX's), with their own identity
    independant of their actual glyphic representation. I am not
    discussing about the typesetting of these grapheme clusters but
    really about the textual semantics of such combining sequences
    with an invisible base character, affecting all their properties and
    not fully described in the various standard annexes. Due to the
    huge legacy use of SPACE+diacritics in legacy text, and the
    already normative parts of some standard annexes, it will be hard
    to correct the behavior or change the text of these annexes.
    And it's where a new better base character than SPACE could
    help solve cleanly the ambiguities.
