It's still a switch every port is in the same vlan that can't be changed, I'm guessing what you mean by "really can't see the benefit in most domestic systems for a switch" is a switch that can carry multiple VLANS AKA 802.1q.
I use 3 x Linksys LGS308P to carry multiple vlans round the house over Devolo powerline adaptors, I have User, Guest, IOT, DMZ and Voice VLANS and also carry 3 of these over a Ubiquity AC Pro access-point.

You'd be lucky to find a hub these days :)
