I think that this should be done on the network level by providing a DNS Server via DHCP or include filtering in your router if you are afraid of users changing the DNS Server (but maybe it’s better to lock the network settings in this case).
But I see that not every User has the possibility or ability to do it this way. therefor having the option to do it in the OS is feasible for these users.
Most other circumventions require the child to know what they’re doing, while a mobile hotspot is something they would naturally use when outside of the house.

That becomes useless as soon as the child discovers the hotspot feature on their phone.
As soon as the kids get smart enough to circumvent such measures, they hopefully know their way arround the Internet
