well, it is \mathdefault that is used and then gets set ... so default 
suits well (something latin in the name just sounds weird)

i guess many math users don't agree with you as tex lingua and behaviour 
is kind of default ... also, it will take a while before wordprocessors 
provide the right visual clues

These, and the sans-serif math styles are added in error of the idea of expressing math semantics, as pure math uses serifs, and applied sciences may use sans-serif. In computer code, in the past, like the 1980s, one did not care about monospace in books, and there is no semantic difference between styles. Keywords might for example be displayed i bold, but there is not semantic difference to when they are not.

pure math is fuzzy ... many domains and habits

there will always be some kind of escape

also, the lack of an upright alphabet in unicode will always make some 
'x' in the input either math of text so one also needs to indicate where 
math starts and ends
