What would be the consumer for that kind of flow? It makes sense on switches, but for a single device, it would be hard to find a reason. We can do 4kUHD way under 1Gbps. We don't get over 1Gbps internet at home. We can't write that fast to any permanent medium. Even RAM will slowly start being a problem if the DDR4 bandwidth is only 6 time higher than 10GbE.
