<p>I might take it a step further and prevent a question from being posted if it only involves software tags. While it might not be possible for Stack Exchange to prevent a question from being posted if it only contains certain tags, the idea appeals to me for the possibility to alert posters that the question is likely off-topic. Consider <a href="https://stats.stackexchange.com/questions/558779/looping-over-pandas-data-frame-cells-for-counting-values">this</a> from today, which only has the <a href="https://stats.stackexchange.com/questions/tagged/pandas" class="post-tag" title="show questions tagged &#39;pandas&#39;" rel="tag">pandas</a> tag.</p>
<p>I came to Meta to post something like this question when I saw that <a href="https://stats.stackexchange.com/questions/tagged/pandas" class="post-tag" title="show questions tagged &#39;pandas&#39;" rel="tag">pandas</a>-only question.</p>
