<p><em>I am providing an answer so to bump the question and close it with some conclusion.</em></p>

<p>Personally I'd considered <code>[dirac-delta]</code> tag useful. The question already got eight upvotes and one negative (?) comment by <em>Carl</em>. I'd say that the response to this idea is positive, so I'd consider creating it.</p>

<p>So to close this issue: is there anyone who does not agree with this idea? Are there any more arguments against it?</p>

<p><strong>EDIT</strong></p>

<p>Since there is not much interest in the thread <em>and</em> it got rather positive response, I created the <a href="https://stats.stackexchange.com/questions/tagged/dirac-delta" class="post-tag" title="show questions tagged &#39;dirac-delta&#39;" rel="tag">dirac-delta</a> tag and started re-tagging.</p>
