There has been significant time since RFC3697 and the lack
of applications may indicate that this field (with
the exception of NIMROD) may not have a use at all.


I've been watching this discussion with mild puzzlement.

There is (basically) nothing that the routers need to do with the flow label. Whatever they might end up doing with it would likely mostly fall under the control plane, so it doesn't need to be put in the hardware.

No, that's wrong if it gets used in line speed QOS classifiers. That's
what I'd expect in load balancing.

So what's the problem? Do you want to try to reuse the "basically unused 20 bits" for some local purposes? That's not going to be allowed.
