I know! That's a behavior chosen by the AT and we shouldn't be trying
to override it. Some ATs have different default behavior (e.g,
VoiceOver). Most popular AT allow users to configure it.

Even if we wanted to encourage them to do something else, that
wouldn't require a change to the existing accessibility hierarchy.

They are indicated to the accessibility hierarchy and AT do give users
options, so this requirement (which I agree with) is already met. And
some AT already have default behavior that alerts users.

If we think the default behavior of JAWS should be different based on
the information already in the hierarchy, we should take that up with
Freedom not try and override their defaults by changing what goes into
the hierarchy.
