But this is not universal solution.
Suppose I want to use serif bold italic font for vectors and sans bold
italic for tensors (this is recommendation of NIST, see sp811.pdf on
nist.gov). Of course I could enter vectors and tensors as symbols from
appropriate unicode slots but what if my publisher says me that vectors
should be in sans bold and tensors in serif bold italic? So I define
commands, like \vect and \tensor to markup what symbols are verctors and
what are tensors.
Therefore I consider context (as well as LaTeX) as sort of markup
(mix of procedural and descriptive markups).
Returning to original question: I don't check but AFAIU one can define
your own typescript and choose what fonts are used in math mode (mm?).
If current typescript (modern?, latin modern?) doesn't have bold greek
letters for math one should define new typescript and use for mm (math)
font which have bold greek letters.
P.S. I could be wrong with terms.
