Most math fonts come only with a regular style which provides upright, italic, bold and bolditalic symbols but all of them part of the same font, only a few fonts provide also a bold style (which is usefull in sections) which comes also with upright – and sometimes bold – symbols.

\setupbodyfont[xits] …

The STIX fonts, and XITS then, support Unicode math semantic styles. So perhaps the TeX commands should expand to these:

what tex commands ... we're talking characters and they don't expand there is a pseudo bold mode but the number of bold symbols is small so it's not that useful
