Unfortunately that's not in-keeping with the backwards compatible nature of HTML5, if we were to specify that as the parsing approach from now on it would cause a major inconvenience to anyone actually trying to use that feature when some browsers have picked it up and others haven't.

This is by design.  A body element will wrap the body in the DOM even if there's no body tag in the markup, AFAIK this is partially to document the existing behaviour of not-so-modern browsers (which, of course, we have no influence over); just have a look at how the DOM is structured in the modern browser of your choice - in my case Chrome:

<html><head>
<title>header and footer outside body</title>
<style>
body {border:1em solid #7f2424;}
header {border:1em solid #247f24;}
footer {border:1em solid #24247f;}
</style>
</head> <!-- I wish the <head></head> tags was called <meta></meta> instead. -->
<body><header>
This is the header of the document!
</header>

This is the main content of the document!

<footer>
This is the footer of the document!
</footer>

</body></html>

This feature would be a U-Turn in HTML5 and I can't see any browser vendors going for implementing it at risk of 'breaking the web' … and I agree that there is a major risk of that.
