Default [Q] Q: PIE in App Immersive

I know 4.4 B1 has changed PIE to enable only in quick-settings immersive.

I was wondering if there is a way to re-enable PIE in app-immersive? Or if not, any plans to bring it back?

I really enjoyed having PIE auto-enable when an app was in (non-system) immersive mode.
