Hmm.  That seems odd here, though.  Are we expecting people to start
using <figure>/<details> without any ability to change their CSS?
Again, there are already issues surrounding the recommended use of
<h1> that will require alterations to existing stylesheets that may be
expecting only a single <h1> to exist on a page and style it
accordingly.  Might as well just layer all the necessary revisions
onto <h1>.

I mean, I've got live CSS that would style <dt>/<dd> badly when used
in <figure> and <details> right now, because I never expected them to
appear outside of a <dl> when I wrote the code.  I'll have to change
some styling no matter what to make things display correctly unless we
invent an entirely new element.
