<p>We as a community, or as moderators, have no way of adding it. It is a kind of change that can be done by the StackExchange developers.</p>
<p>Personally, I see no reason for adding it. Mathematica is far from the most popular among statisticians and data scientists. Moreover, we support <span class="math-container">$\TeX$</span> and if you look at the posts, most of the users have no problem with using it, so it would solve a problem for a small group of users who know Mathematica but don't know <span class="math-container">$\TeX$</span>.</p>
