Why <div> and not <p>?

What we could do is simply say that any run of inline content between 
block-level content implies a paragraph (though without a <p> element 
appearing in the DOM), much as we currently define that multiple <hx> 
elements in the same <section> element imply a section (though without a 
<section> element appearing in the DOM).

This would mean that:

   <body>
    <h1>Demo</h1>
    Unmarked up text as a child of BODY is fine, it implies a
    paragraph around it.
    <hr>
    This is a second implied paragraph as the HR element is a
    block-level element.
    <aside>
     This sidebar doesn't require an explicit P element anymore
     because the text gets a paragraph implied around it.
     <ul>
      <li>This list implicitly becomes inline-level, since it is
      within an element with children that all are valid as
      inline-level content.
      <li>However, <em>that</em> would mean that:
       <p>This paragraph is invalid, because it's a block-level
       element in an inline context.
     </ul>
     This text is part of the same implied paragraph as the text
     before it and as of the list.
    </aside>
    <section>
     On the other hand, here we have a FOOTER element at the end
     of the section.
     <ul>
      <li>Therefore the parent section element of this list has
      block-level children.
      <p>Which means it is fine for this list to contain paragraphs.
     </ul>
     <footer>
      ...
     </footer>
    </section>
   </body>

That's somewhat confusing. I think if we go down this road we should 
remove the ability for certain elements to act as both inlines and blocks, 
as otherwise authors will get very confused as to when they're in an 
implied paragraph and when they're not.

Do you mean markup like this:

   <ol>
     <li>
       text
       <p> text

...or something else?
