Not all the links will be Terabit, right? It's for them - they're likely to be able to fill their uplinks, or have some congestion / traffic ordering concerns, and all the traffic from the non-TBE sites isn't just uplink traffic - stuff is coming back to them. And if it's coming back from the main location that has TBE, then you'll have congestion issues on the return side of the flow...

Speed can mitigate QOS concerns in some regards and in some scenarios, but certainly not all of them. People often think speed is a cure-all, and it's not...

Faster optical links can easily lead to increased nodal delays. And as the number of nodes in a network multiply, so can the cumulative delays. If the bandwidth is there, it will get filled, most likely with irrelevant stuff, so with a bit of luck QoS will help move along the latency-critical information ahead of the dross. At least we hope!!
