I do not think the law provides guidance here. The signal is only required when children are the primary device/account users. So one model would be any initial account set up is automatically considered the 'account holder' and not a child account. Then it would be prerogative of the 'account holder' to set up child accounts or not. That seems to fit into the spirt and literal parts of the law.

So grep/ls/etc are all installed as part of that 'account holder' and do not need to do any age verification.

The signal only needs to be checked when the device/account user is a child and when downloading apps. I think an unfortunate consequence here is that the literal definition of the law says package managers probably can not run on children accounts without jumping through a bunch of hoops. Which is bad for children learning code/computers/etc.

The first thing I would change about this law would be:

> (b) (1) A developer shall request a signal with respect to a particular user from an operating system provider or a covered application store when the application is downloaded and launched.

Any application that does not need to know a users age should not be required request the 'signal'
