It's still not as trivial as you're making out and leaves the user with a less than ideal experience.

Disabling the radio on the hub means the hub is still acting as DHCP server and Firewall to the network - this is historically where most of the Hubs issues lie. Just plugging in a consumer router and switching the hub to modem mode is far, far better. You can't use modem mode with the Unifi AP's as they don't do DHCP, they're literally just AP's.
