There were a plethora of math characters:
The bold italic is hard to document usage of, as in the past it was
expensive to keep fonts - one would substitute something else. So it
would be silly not to add it in en electronic medium that easily can
The double-struck style characters were completed to all upper and
lowercase letters. Monospace and sans-serif are strictly not semantic
styles, but can now be used as such, in view of the additions. For
relations, there might have been cases of reversed characters, even if
no such use could be documented.
The principle here, though, is that there are well-known principles of
usage, limited by the physical (led) typesetting techniques, and the
additions just augments what is necessary to fulfill those principles.
