<p><strong>Update</strong>: the tag was burninated.</p>

<hr>

<p>In my opinion, 'best-practices' is a meta tag and should go. On contrary to 'self-study' it does not have a clear scope which would justify keeping it here. In summary, it is what you said:</p>

<blockquote>
  <p>.....but its value in identifying content related to professional practice (which is the use it currently seems to serve) would be almost entirely diluted....</p>
</blockquote>

<p>In response to Silverfish's answer:</p>

<p>I'd rather see 'best-practices' leaving, without needing a substitute tag.</p>
