Sorry for being the dunce here, but is anybody saying otherwise?  Whereas
XML _requires_ that you close every tag, HTML5 _should allow_ you to close
any tag.  I agree with what was said previously about considering something
like '<select /></select>' invalid, but if somebody's suggesting that
something like '<img src="..." />' or '<br />' should also be invalid,
I disagree.  Validators and UAs should accept singleton tags _with or
without_ the self-closer.

Am I totally misunderstanding or missing the point here?
