Reading your description makes me think that you're more displeased with the
<hn/> elements than you are happy with the <section/> element. I've never had
issues promoting headers or moving content around, and I'm not clear that
<section/> would help in any of these circumstances. Nested sections using
different <hn/> elements seem more confusing to me than just using the <hn/>
elements.

Certainly they're defined by headings. The issue is *which* heading.
If you move sections around (for example, promoting what was originally a
subsection to a full section of an article) you have to manually renumber all
of your headings to get the semantics right. This is a ton of meaningless
search-and-replace.
If you use a site template, you have to constantly remember that your content's
most important heading is <h3> (or whatever), since the <h1> and <h2> tags are
used in the template.
If you are writing blog posts, you have *no idea* what your top-most heading
should be. If the post is looked at all by itself, perhaps it gets <h1> or
<h2>. If the post is displayed among several others on a page, perhaps it
should start with <h3> because the higher tags are taken up by category
headings separating out the posts.
If you are copy-pasting someone else's code into your own (for a blockquote,
frex), you have to adjust all the headings, because the original author has no
way of knowing what level of heading you're using in the piece you're quoting
him in (and obviously has no reason to care).
These are just the use-cases that I could come up with off the top of my head.
All of these are relatively large inconveniences with the current <hn> nesting
scheme. They are all solved by using <section> tags, since that 'resets' the
<hn> hierarchy by explicitly sectioning the content.
Nobody is being forced to section all their content using <section>s
explicitly. That's why the <hn> implicit sectioning algorithm exists - it's
easier to work with. However, there are many situations when being able to
explicitly define sections is a great boon.
