I suggested <p> to be allowed as child, myself. I spotted one response, 
from Doug: 

I'm not sure, though, that he is right that allowing a <p> could make 
the <hgroup> be interpreted as header rather than a heading.

Issue: The name '<hgroup>' alludes to 'group of <h[1-6]> elements' - 
like '<colgroup>' refers to 'group of <col> elements'. So, if one 
allows any other flow content than h[1-6] as children, then the name 
would have to change.

Issue: In your example, what about h[1-6] elements inside the <div>? 
Perhaps a designated <subtitle> element would be better then? And if 
so, why not drop <hgroup> entirely and allow a subtitle element inside 
h[1-6] elements?

The good thing about only allowing h[1-6] elements is that we only 
allow the elements that can contain 'heading material'. The reason why 
I suggested <p> as sub element container is also the content model: its 
content model is very similar to that of h[1-6].
