ARIA 1.3 - User Agent support

This section seems to have an each-way bet, and then take an each-way bet
on the results of that. I think it should state that "User Agents SHOULD
use ARIA information in content to provide the same behaviour as for the
equivalent native semantics of the host language".

The defining line between a user agent's interface and an assistive
technology is extremely fuzzy in reality - since the ability to zoom is
assistive although it is part of any modern user agent.

I do not understand the reasoning behind the statement

"Furthermore, for many user agents it may be strategically preferable to
introduce native support for given WAI-ARIA features only once they become
part of the host language. In this case the user agent would support the
now native host language feature, but may choose to not provide parallel
support for the WAI-ARIA markup (beyond continuing the accessibility API
support for legacy content)."

And would appreciate a pointer to discussion that explains why it is there.

cheers
