Well, `org-html-headline' does a lot and I'm trying to rewrite as
little as possible. Actually, i already wrap `org-html-headline', so i
could fix the :CUSTOM_ID on the way in. I think i was looking for a
solution to both the wrapper element and id in the same place (a
filter).

What I think is missing is a way to customize the element used for the
wrapper, and possiblly the id/class prefixes.  The simple solution
would be to add an `org-headline-wrapper-element' customization
(defaulting to "div"), or if allowing change to the id and class:

       '("div" "outline-container-%s" "outline-%d").

If you were to over-engineer it,something along the lines of the way
the latex exporter specifies the headline hierarchies for one of the 
document classes would work :}

Likewise, it would make sense for the `org-html-divs' to become a list
of '(element . class) instead of a list of just classes. e.e.g

(defcustom org-html-divs '(("header" . "preamble")
                           ("section" . "content")
                           ("footer" . "postamble"))
