Wrapping single elements would be of limited usefulness (though still better than nothing).

What's more demanded is ability to pseudo-wrap _multiple_ sibling elements, so that we could style, for example, `DT`/`DD` groups as a single thing without need for wrapping each such group in its own `DL` (we can't wrap them in `DIV` per HTML spec) and wrapping each such `DL` in `LI` inside `UL` to preserve marking items up together as a solid list.

For example, if we need to style each `DT`/`DD` group, we are currently forced to do this:

����<ul>
��������<li><dl>
������������<dt>Foo</dt>
������������<dd>Bar</dd>
��������</dl></li>

��������<li><dl>
������������<dt>Lorem</dt>
������������<dd>Ipsum</dd>
��������</dl></li>
����</ul>

With CSS preudo-wrappers, we could have a single continuous `DL` in HTML:

����<dl class="example">
��������<dt>Foo</dt>
��������<dd>Bar</dd>

��������<dt>Lorem</dt>
��������<dd>Ipsum</dd>
����</dl>

and then style `DT`/`DD` groups inside it somehow like this:

����DL.example > DT {group-open: myGroupName; }
����DL.example > DD {group-close: myGroupName; }

����/* Show green border around each `DT`/`DD` group. */
����::group(myGroupName) {
��������border: 2px solid #0d0;
����}

By the way, each such group could then also be additionally wrapped (as needed) in something like single-thing wrappers you've proposed.
