BTW, \frac is one of the few math macros which can be inserted with
C-c RET'.  Probably because of it accepting two arguments.  It's a
bit bewildering that many macros from LaTeX-math-default' are only
available through the menu, i.e. there is no tab completion.

tex-fold.el will now use the content of <mode-prefix>-fold-*-spec-list
variables if defined.  These variables can contain mode-specific
macros, math macros or environments to be folded.  I've currently only
defined special variables for LaTeX mode and haven't documented the
feature yet because I want to see how it evolves.

The variable LaTeX-fold-math-spec-list' is now used for making the
macros defined in LaTeX-math-default' available to tex-fold.el.

Next steps would now be to sort out which math macros are relevant for
which modes and dissect LaTeX-math-default' accordingly into other
mode-specific variables.  The macros in those variables could then be
used to construct the menus of a general TeX Math minor mode as well
as to make them available for insertion with C-c RET'.
