Well, as I sit here, my apartment edge router gets a /60 from Comcast, and burns through them pretty quick. A subnet for the 4 wired devices, another for the 2.4Ghz wireless, another for 5ghz wireless, and if I enabled them another 2 guest wireless subnets.. and then more for any VLAN I might set up. If I lived in a large enough house, I'm *already* out of enough address space to easily prefix-delegate to a second router at the far end of the house. And yes, this *is* a setup where there's only 1 or 2 devices per most subnets. So no, the idea is *not at all* to see how we can cram as many devices as possible onto a subnet. The idea is to set up a networking environment where it's as easy as possible for even fairly stupid devices to be able to auto-configure and join in. And there's *really* good security reasons for your FizzBin 5000 that wants to be a IoT device but you don't really trust, to end up on a different subnet from your laptop....
