Got that part, but what throws me is, in order to install a Google app on that secondary "google" profile, don't you have to first install the Google app on the main profile so that you can then push it to the secondary profile?

Wow, this is impressive. I had heard about profiles but never got into the detail and never really understood the benefit. So, a cool way of using this it to have a FOSS only space under the main admin profile and the build up a second "big brother" profile where I stack some annoying apps that in a way or another I'm forced to use like banking app and what's app. When the "big brother" profile is shut down, nobody tracks you. Would that be correct? If this is true I'm here asking myself why on earth people are not harnessing this more.
