The AT should not ignore landmarks in "document browsing" mode so for this it should not matter if you are in "application" mode. Flash supports platform accessibility APIs in the form of MSAA. What they do not do at this point is support a richer accessibility API which would support the entirety of WAI-ARIA. I believe Adobe is looking at the end to end solution but I don't know what progress they have made to supporting an extended API set like UIA or IAccessible2 in the flash player. Matt May can speak more to this. My experience with Flash is that when it is accessible it works when you are doing application mode style navigation. Browsing the virtual buffer did not work so well. So, I would agree that having role="application" would be a great addition to Flash. Matt, what are your thoughts?

In a sense, because Flash isn’t accessible on all systems, and because the interface is very different from the web browser’s interface, the author is promising the user something they can’t always deliver, or may not deliver in the way the user expects. In theory, on the platforms where Flash is accessible, the Flash player could/should communicate role, state, and property information directly to the accessibility API, instead of going through the browser via ARIA.
