Agreed. That’s how the thinking goes.

For my own part, I did not think that way about e.g. <table 
role=presentation>, but I did think that way about <img

Has the component for reporting ARIA bugs been set up?

Here are some things that I think ARIA 1.1. should be updated with:

1. Presentation role section should have more examples, to explain the 
”edge” cases, such as the fact that role="presentation" does not 
prevent AT from looking into the subdom of resources referenced via 
@src (and I suppose of @data, of the object element). Would also be 
good to exemplify edge cases such as <video role="presentation"> - what 
its effect is (not).

3. Definition of ”descendants”, in connection with the accessible name 
calculation, so that readers of ARIA understand that ”descendants” is 
not only only child elements but also elements of resources that a 
linked to the element via @src, @data or (I think) otherwise.

4. Clarification, for role=Presentation, of what ”implicit native role 
semantics” covers and what it does *not* cover. Definition and examples.
