That's true but the existing ones could have been classified as specific for their intended use eg U+2102 DOUBLE-STRUCK CAPITAL C = Complex numbers leaving U+1D53A free to be defined as a part of a generic alphabetic run MATHEMATICAL DOUBLE-STRUCK CAPITAL C But it's only an annoying quirk, as you say it can be programmed around so probably not worth changing now, as change introduces its own problems.
