Sure.
Note the related ISSUE-708 and ACTION-1681:

See the mappings for presentation in the mapping table, where it states
how presentation/none applies to tables, lists, etc.:
http://w3c.github.io/aria/core-aam/core-aam.html#role-map-presentation

From the ARIA 1.1 specification for role presentation/none:
" ...the user agent MUST always expose global WAI-ARIA states and
properties to accessibility APIs, even if an element has an explicit or
inherited role of presentation".
http://w3c.github.io/aria/aria/aria.html#presentation
Technically, this isn't a core-aam issue. What is a core-aam issue is
that its current wording doesn't clearly reflect the above stricture
from the spec. Is the spec going to change in this regard?

We need this for the core-aam work. I put it on yesterday's agenda, but
we didn't get that far.
