Apparently, the Stacks project can load a MathJax extension called xypic.js
(check the source code) and then has access to \xymatrix
in their MathJax-$\LaTeX$ code. Would it be possible to add this to MO? Diagrams are always quite difficult to do when you can only use matrix environments.
It appears that XyJax is developed independently from MathJax. As a result, MathJax will not support nor test XyJax. This makes integration into MathOverflow difficult since we need to have reliable support for new features. We cannot implement such features without a suitable support plan from the XyJax developers.
