If I may try to express what I perceive the problem to be, we have been told 
that (for example, and there may be others) certain security gateways DO change 
the value of that FL. And presumably, for good security-minded reasons. So to 
say FL MUST NOT be changed is, I gather, factually not possible anymore.

I agree that "since you can't detect whether it's been changed, mechanisms 
using the flow label for some purpose must be robust against unanticipated 
changes," however I think the hard nut is this MUST NOT be changed requirement.

So for example, the load balancing use of FL must not cause the session to 
break if FL has been changed.
