I agree with you, it would be a useful fallback. It would never be a
primary solution though, it is essentially screen-scraping, and would have
the same disadvantages as screen-scraping approaches that were used before
accessibility API:


* Accessibility APIs make it the app developer's responsibility to
implement propper accessibility, this is by design. App developers know not
just their app, but also the content associated with it, and therefore can
implement an accessible experience that may be different from the visual
layout and yet more efficient for AT users. An example is the list of
recommendations on Youtube. Visually they are in a grid, but the screen
reader sees it as a list of headings.
* One of the most important requirements for a screen reader is
responsiveness. The quicker a blind user knows about an update in the
interface, the better. Even a slight delay before an announcement may
result in an interface that feels sluggish. This is why blind users often
use speech at a very fast speaking rate. A pattern-based approach will
always be slower than just reading the state via the accessibility API.
* It is dependent on the visual layout, which means accessibility may break
just because an app got new icons, or a few components shifted position.
These things are independent from the accessibility API.


Still, it may be a useful approach to consider for special edge cases, and
I am interested to see what happens in this space.
