FWIW, I use Google Wifi, having bought a 3-pack on sale around the holidays. I did not setup any sort of "completely separate backhaul network for client mesh handover". This may be an implementation detail of some sort. The setup experience is pretty much plug-and-play.
I'd buy them again in a heartbeat, and I'm normally quite hesitant to buy Google products.
