<p><strong>Rather not.</strong></p>

<p>While I agree that such a tag could be useful, it seems that the combination of <a href="https://stats.stackexchange.com/questions/tagged/bayesian" class="post-tag" title="show questions tagged &#39;bayesian&#39;" rel="tag">bayesian</a> and <a href="https://stats.stackexchange.com/questions/tagged/frequentist" class="post-tag" title="show questions tagged &#39;frequentist&#39;" rel="tag">frequentist</a> tags serves more or less the same purpose. There are 95 threads tagged with these two tags together, see <a href="https://stats.stackexchange.com/questions/tagged/bayesian+frequentist">https://stats.stackexchange.com/questions/tagged/bayesian+frequentist</a>, and looking through them it seems that most could in principle qualify for <code>[bayesian-vs-frequentist]</code>.</p>

<p>That's why I think such a tag is not particularly needed: we <em>already</em> have its functionality.</p>

<p>In addition, its very name would imply some amount of confrontation, and I doubt this would be beneficial for our forum.</p>
