I had in mind software that normalized documents to use explicit  
sectioning elements, since the spec encourages authors to use explicit  
sectioning elements:

    Authors are also encouraged to explictly wrap sections in elements of
    sectioning content, instead of relying on the implicit sections
    generated by having multiple heading in one element of sectioning
    content.

...but, since it's not allowed to use multiple <body>s, the case above  
can't be normalized to explicit sections without changing the outline.

I don't feel strongly about it, but I think the spec should rather  
encourage authors to not let content "slip out of their parent" as in the  
case above (because it feels dirty), than to encourage authors to use  
explicit sectioning elements (I think implicit sections are fine so long  
as they are inside the parent sectioning element).
