Great news on the advancement of the Math extension.
I would like to point out for those unaware, there is also the SimpleMathJax extension which uses the same MathJax backend, but instead of requiring your own service on the backend, it does the substitutions client-side. SimpleMathJax is what we use for our clients' wikis e.g. https://demo.qualitybox.us/wiki/Math
