Well, one reason could be that there is no such character. (Did you
mean U+1034A GOTHIC LETTER NINE HUNDRED?)
All the Roman numerals I can find in the standard, except U+2183 ROMAN
NUMERAL REVERSED ONE HUNDRED, have a value in the "numeric value" field.
(Perhaps the actual numeric value of U+2183 is not known.) To derive
the numeric value of the combination U+216D plus U+216F, one would have
to apply the rules of Roman numerals, which is why these aren't digits.
