But not > much, by legacy o/s releases. more to the point, if you were going to implement a forwarding device, do you depend solely on the flow label? This gives end-user device control over the hashing path on a purely discretionary basis. I.e. and end user can change the flow label and consequently make their own decisions about which network path to use, without affecting any other transmission characteristic of the network flow, e.g. port numbers, IP addresses, etc. Operationally, flow labels can cause grief. APNIC had a blog posting on this a while back https://blog.apnic.net/2018/01/11/ipv6-flow-label-misuse-hashing/ Most devices allow the operator to selectively use flow labels as an entropy source for hashing.
