Perhaps so.
Still, how to switch? If the "switch internals" is just a token-ring + ARP table (IE: each port remembers the mac addresses its serving, and token-rings the data around), the switch will have ~10GbE for all-ports, but only a max bandwidth of 10GbE before it starts losing packets. (Ex: Alice <-> Bob <-> Charlie <-> Dave with only 10GbE each link. If Alice talks to Charlie and Bob talks to Dave, then the Bob -> Charlie needs 20GbE, so half the packets will get dropped)
This isn't a full switch classic.
Maybe a "Hub classic" isn't enough, since that keeps the ports needlessly active as you noted. But I don't think the full 80Gbps bidirectional is needed for an 8-port home-consumer (or even many prosumer) environments.
The full 10Gbps switches all get quite hot, probably due to drawing a ton of power. I'm thinking that some simplified architecture is needed to reduce power (by trading off and reducing bandwidth)
