Yeah, that's basically what Apple offers today on their thunderbolt monitors (except those still need a separate power cable). Hopefully we'll actually see a wider adoption of the concept once it's on commodity USB-C instead of the massively expensive thunderbolt.
Only problem I've seen is that the thunderbolt hubs cost over $200, plus the cost of the cable. And even then they only have a few ports.
It's an interesting comeback for the concept - it reminds me of daisy chaining PCs on their serial ports for playing Starcraft:
