I'm a little concerned about this too, but I suspect doing the dbus call off the main thread will be enough work that we should get real numbers before deciding to do it.

I suspect this is correct, but I'm ok with not cleaning up the existing dupplicated code in this bug. What I'd suggest is put the function to check the dbus status in the a11y namespace and make it non-static and use in the widget check.
