I'd accept such a (backward-compatible) change, but here's some
nitpicking.

Does that play well with `TeX-math-close-double-dollar'?  I'm not
completely sure if closing of single or double dollars and placement of
point should be controlled by the same variables.  What's the result of
typing $$$ when both variables are t?

Use `blink-matching-delay' instead of hard-coding 1.  Please change the
other `sit-for' that's already there, too.

And such a user-visible change needs some documentation below the node
(info "(auctex)Quotes").
