This isn't used on Windows; see bug 1759971 for that. Parts (but not all) of it seemed to be used by Orca. We should probably assess what is needed and what isn't before doing any work.
We expose a bunch of object attributes from the DOM for various MathML elements; see instances of AttrFromDOM in accessible/base/MathMLMarkupMap.h. Furthermore, there is HyperTextAccessible::SetMathMLXMLRoles, some of which is calculated from the a11y tree structure, some of which depends on DOM and layout.
