WAI-ARIA 1.1: role= None and role=presentation

I suggest two alternatives with my preference for the first:
i. If the perception is that developers do not understand use of role=presentation, then the solution is to clarify its usage in the specs / education material. Makers of user agents / AT should not be required to make a change if they already support role=presentation.
ii. Sure role=none makes better sense than role=presentation from a wording / semantic perspective.
Instead of retaining role=presentation, consider deprecating role=presentation.
Deprecating it will give a clear signal to makers of user agents / AT and in the interim, validators can flag "warning" for role=presentation.
Defining two roles with identical functionality will make it difficult for makers of user agent / AT. Some will support it sooner or later or not at all. They may not regard supporting role=none as critical if they already support role=presentation.

Developers will need to cope with this problem by setting role=presentation and role=none to deal with user agent variations.

Thanks,

ARIA doesn't need two roles for same thing, role="presentation" can go away.

My preference goes to option number two, but I can see that this involves more work for all parties.

Moving to ARIA 2.0 as we don't expect to address deprecation of presentation until then.
