Because it existed as a single element in one of the pre-existing, widely
used, encoding standards.
As this is explained with great details in the Unicode Standard, some
characters are encoded in Unicode for round-trip compatibility rather
than for actual use. These characters can be detected by looking at
their properties: they always have a (usually compatible) decomposition.
A clue: the name of the U+33xx block is "CJK compatibility"...
