Hmm! It is a valid point actually.
Oh and here is some food for though. This works in all latest browsers. 
Opera and Firefox have same behavior, while Chrome is a tad different, 
and as IE is unable to style unknown tags sadly.

<!doctype html>
<html>
<head>
<title>Test</title>
<style>
   aside {border:1px solid #bf0000;white-space:nowrap;}
</style>
</head>
<aside>
  Just testing aside outside body!
</aside>
<body>
<article>
   Main part of article.
</article>
</body>
</html>

As you can see the aside is outside the body, all latest browsers seem 
to handle this pretty fine.
http://validator.w3.org/ on the other hand gives the error " /Line 12, 
Column 6/: body start tag found but the body element is already open.| 
<body*>*|"

Now, either that is a bug in the validator, or the body is automatic.
And sure enough, removing the <body> and </body> tags the document 
validates, and none of the browsers behave differently at all.
Is the body tag optional or could even be redundant in HTML5 ?

I don't mind really, as currently I only use body to put all the "other" 
tags inside, so not having to use the body tag at all would be welcome,
though I suspect a lot of legacy things rely on the body tag.
