Re: [csswg-drafts] [css-fonts-4] [varfont] Supported variation font axes and font features are not discoverable

Would it be possible to extend this to include access to the [OpenType 'MATH' tables](https://docs.microsoft.com/en-us/typography/opentype/spec/math)? 

Some math-aware fonts include metric information in these tables which are necessary in order to do proper mathematical layout (i.e. to correctly position arguments on display operators such as integrals or to use the correct line thickness for fraction bar or square root over bar). 

Software libraries doing math layout such as MathJax or MathLive have to manually parse font files in JS or, more realistically, hardcode these metrics for a specific font.
