I was doing some testing with potentially using a secondary profile as a child profile. However, I realized you cannot login to a secondary profile on a clean boot without first logging into the owner profile. I can imagine there might be some reasons for this from a development/system functionality standpoint, but I am curious whether this is something that might be able to be changed in the future so that a secondary profile could be used right away from boot. Otherwise, if the phone dies/reboots without the owner profile controller present it essentially becomes a glorified brick.
