    would this answer also be true for the mathematical alphanumeric symbols [U+1D400,U+1D7FF]?

    Mathematical typesetting requires much more than glyph variation, especially if complex fractions are to be represented. So, one could have ruled that the glyph variations are also to be supported at a higher level. But not if the character set of another standard (aimed at mathematical typesetting) has been imported into Unicode.

    > Why is there a special Unicode character U+210E for it?

    The short answer: because it was required many years ago for round-trip
    mapping to another standard.
