Please describe how this change could adversely affect legacy pages, 
given that the alorithm is explicitly defined to deal with current usage 
of h1-h6 as well as when they are nested within section elements.

I do not understand how that markup illustrates your point.  HTML5 
allows the h2-h6 elements to be used within nested sections in place of 
h1 elements so that authors may achieve better compatibility with 
current browsers.  The heading structure for that would be semantically 
identical to the equivalent markup using all h1 elements instead.
