This time I'm not convinced. I see this as a ploy to quarantine apps they dont like but are legitimate e.g "Yet another call blocker"

I’m not sure about this feature. I’ll need to see some use cases. If you’re just talking malware protection, I’m not sure why we need a new quarantine state. The app should be completely completely disabled or removed if possible, and if you’re worried about false detections, perhaps it would be better to tackle the false detection rate from a different angle.

It's services can't be queried. This is huge. If you quarantine the Google services then the other apps can't use them to break through your firewall

What...?

Cool

Doesn't sound very useful to me
