Why does the size of the spec matter? Surely the benefit to authors far, 
far outweigh the benefits to the spec community?

It's not much work, it's a single sentence. It's there so that the markup 
reflects the syntax. If we did it the other way around, you'd be 
complaining that this:

   <body></body><!---->

...represented a body element containing a comment, whe it obviously 
doesn't.


> If body can be omitted, then why can't an empty body by omitted?

Oops. This is an error. It used to be that omitting the element's tags 
altogether wouldn't imply the element, but we've changed that now. Also 
fixed for </html>.
