<p>There seems to be agreement that such a tag without a tag wiki and used only thrice, without consistency, should be removed.  And that maybe that could have been done without raising the issue on meta. @amoeba wrote in comments that " To be honest, when I come across a tag with only few uses that lacks a wiki excerpt and a clear scope, I just silently remove it myself without raising the issue on Meta. It does not happen very often, but I did a couple of times."</p>

<p>So I just removed the tag.</p>
