you may be misunderstanding, currently all browsers that implement acc API
semantics for headings implement:

h1 role=heading level=1
...

h6 role=heading level=6

The HTML5.0 CR spec is meant to reflect interoperable implementations, thus the
dropping features that don't currently have interop implementations (see
https://www.w3.org/Bugs/Public/show_bug.cgi?id=24812). 

It has been agreed that the outline algorithm
(http://www.w3.org/html/wg/drafts/html/master/sections.html#outlines) does not
have any browser interop requirements and therefore will stay in 5.0 and live
on in 5.1. The requirements to implement the separate acc layer part has no
interop implementations and is the subject of this bug. If the acc layer part
gets interop implementations before HTML 5.0 becomes a rec then it will not be
removed, if not it will. It will remain in 5.1 awaiting further discussion/
changes/implementation.
