With the STIX Two fonts [1-2], one can choose say Stylistic Set 8 <ss08> for more upright integrals. How is that done in ConTeXt with XITS?
1. https://sourceforge.net/projects/stixfonts/
2. https://en.wikipedia.org/wiki/STIX_Fonts_project#STIX_2.0.0
see stix-two-math.lfg
\setmathfontalternate{whatever}
On MacOS, it does not load the fonts: In the example below (also not working with 'xits' or 'stix'), I get:
fonts           > typescripts > unknown library 'stix-two-math'
fonts           > preloading latin modern fonts (third stage)
fonts           > 'fallback modern-designsize rm 10pt' is loaded

They are installed as system fonts.

Also, though \iiiint now seems defined, the limits are still underneath with the option 'integral=nolimits'.
