Filter which entities a user can interact with (exclude / include)

I would like to configure which entities a user can interact with, using exclude / include filters similar to recorder integration. The reason behind this is to give access my children to HA in a near future (they’re still too young) to control their own bedroom and main entities (like lights), but not other’s bedroom. For example, my daughter can control her own thermostat, not my son’s one. And viceversa. They’re siblings, you know.

Having in mind the multi-instances support in the Android app (and maybe iOS soon), I can give access to parents, neighbours, friends… Each of them to some specific entities for a specific reason.
