I doubt if this will work when we have both ASH and Native Desktop instances
running?

[tapted, 2013/11/15 00:11:51]

Yes that's correct. This function is to capture the current policy that we do
not have both instances running. E.g. the Desktop app launcher has a "Chrome"
app. With policy="both" that should open a browser on the desktop. With
policy="metro OR desktop" that should open a browser in Ash.

Is there a timeline in mind for switching back to "both"?
