I'm opening this meta bug. There are essentially two points:

1) Better Unicode coverage for math symbols. You can see a list in
http://www.w3.org/TR/xml-entity-names/#blocks . In particular,
https://en.wikipedia.org/wiki/Mathematical_Alphanumeric_Symbols is important.

2) Add an OpenType MATH table, and especially the mathvariant subtable which
allows to stretch e.g. parenthesis or radical and draw e.g. summation symbol
bigger in displaystyle mode.

This would important for the MathML rendering in Gecko/WebKit and for various
modern TeX engines (LuaTeX, XeTeX etc).

For more info, see the references at
https://wiki.mozilla.org/MathML:Open_Type_MATH_Table#References
