Thanks for sharing.  I have some comments below:

Do we really need this?  Can we just take the value of
`TeX-electric-math', and make an assumption if it's nil?

This function is LaTeX centric, right?  So I would call is
`LaTeX-make-inline-math' or something and put it in latex.el.

surrounded by `TeX-electric-math' if non-nil, or \"$..$\",

(delims (or TeX-electric-math '("$" . "$")))

Would it be possible to write an ERT-test for feature?

I will have a look, will try to make a suggestion.
