Anyone planning to do this might want to be aware that the validation
process of flowspec does not limit actions.

In practice this means, if you do run flowspec to your customers, your
customers likely can inject traffic to arbitrary VRFs.

I feel RFC should have explicitly stated valid actions for validation
process, which operator MAY change, and any other action MUST cause
validation process to fail.
