I use an alias name in Google play to download all my apps into my Owner profile, then I distribute apps from there to various profiles I've created for different functions. I also created a profile for Google products and included the Play store in that profile, without logging in there.
I never use the Owner profile for anything other than downloading apps and making adjustments to the phone. All network requests from any apps are shut off upon downloading. The Play store is installed in a few of my profiles but I don't bother logging into those instances, they are there only because some apps require both Play services as well as the Play store to be present.
Regarding the dedicated "Google products" profile, if I log into the Play store with my real Google ID while there, will that login conflict or otherwise discover the alias login I have in the Owner profile?
