I wonder if, at all, other fonts will ever be used for MathJax max display?
The 'default MathJax font' is also just the 'default LaTeX font' (CM?). There are countless other, high-quality math fonts, for example the TeX Gyre Math fonts. I'd like to see those one day, I prefer them. It would be not more out of place than the current version.
There are font pairs, too, like TeX Gyre Pagella and its TeX Gyre Pagella Math accompanying font. So you have the same font for both, which is simply beautiful and even more readable I'd argue. I think most people have accepted that text and math fonts are always distinct, when in fact they needn't be.
