I'm no expert at screen readers but I believe the ability to skip text is
built into the reader which is not so for visual browsers. A visual browser
would collapse sections to make it easy to skip text but a screen reader has
commands that will read headers [1]. One can tell the reader:

- Read all Headings
- Read First Heading (ALT+INSERT+HOME)
- Read the next heading (CONTROL+INSERT+ENTER)
- Read the previous heading (SHIFT+CONTROL+INSERT+ENTER)
- Read the first H2 (ALT+CONTROL+INSERT+2)
- Read the next H2 (ALT+INSERT+2)
Etc.

So why search for a solution where none is necessary? Or am I misunderstanding
your point?
