It would absolutely be worthwhile.

Your point is understood, but I must note that the 'class' attribute cannot
structurally group elements. The 'class' attribute groups elements logically
only. The need for a 'di' element type is thus increased, if anything.

This was always a problem in that a definition list item, having no element
of its own, could not posess an ID. For me and for some others, the ability
to assign an ID and to refer to it is the main benefit of the new element
type. Consider the following document fragments.

<a href="#term-XHTML">XHTML definition</a>
<dl>
 <dt id="term-XHTML">XHTML</dt>
 <dd>Extensible Hypertext Markup Language</dd>
</dl>

<a href="#def-XHTML">XHTML definition</a>
<dl>
 <di id="def-XHTML">
  <dt>XHTML</dt>
  <dd>Extensible Hypertext Markup Language</dd>
 </di>
</dl>

In typical Web browsers, the apparent difference between the two is slight.
Regardless, the semantic difference is significant. The effects are felt
anywhere that addressing elements is important: style sheets, metadata, and
so on.
