please sir, can I have a child account

of course you can!!!

How I was imaging the child accounts would be handled with existing api code.

NOTE: this is a discussion point so the test is minimal and my generated username for the child account leaves a little to be desired :)

Not `root`, `admin`.  You shouldn't be able to have root on anyone else's account.  If its actually letting you set that, then that's a bug in gatekeeper...
