So, what you are going to create an element for every ARIA role now? That
is crazy.

Aria landmarks are large perceivable regions in the document marked by the
associated landmark role.

The problem with footer is that by name it sits at the end of the document.
contentinfo pertains to the region that provides information about the
document it is housed in. Why limit information about the content to the
end of a document by calling it footer?

There are 2 issues here.  One is to have an element that can map to the
ARIA main role, and the other to provide authors with an element they
can use to wrap around the content of a section to separate it from the
header and footer.  See, for instance, the markup used on html5doctor.com

For each article, they have a structure like this:

<article class="hentry">
   <header>
     <h1><a href="...">Article Heading</a></h1>
   </header>
   <section>
     <p>...</p>
   </section>
   <footer>
     ...
   </footer>
</article>

The use of <section> in that case is wrong, but it seems that authors
want an element there.  Although if we just want to say use <div> (or no
element) for that case, and just address the more specific role="main"
case, then I can accept <main> as an appropriate solution.

That is still the case with what I suggested, since it's the browser
that would handle the mapping from the appropriate <header>/<footer>
elements to the banner/contentinfo roles.
