Looking into old computer science books, they do not have monospace, and a I recall a Pascal compiler on Mac OS 9 that used styled, non-monospace fonts. So a monospace font may not be strictly necessary, though current UTF-8 plain text does not look good. In Xcode, part of the reason is that one cannot choose font per Unicode code point segments.

we're not talking of the monospace math alphabet (those are already 
covered but the fonts) but about a monospaced font for editing and 
verbatim (handy for manuals explaining math typesetting)

in a similar fashion a bold math font is not about math bold alphabets 
but about a whole bold font with a couple of heavy bold alphabets (handy 
for typesetting section heads in bold that have math)
