For Orbi mesh systems with Parental Control features enabled, it would be great if the ability of new devices to join the network can be controlled. A on/off switch would be practical for locking the known device set or allow new ones to join.
This is a spin of the old-fashioned MAC filtering - which is available in absence of Parental Control feature.
I see this on/off locking switch approach as more user friendly and enhanced security overall - less tech savvy users don't need to mess around with MAC addresses; they just need to lock the network.
