Of course.

Which is, why I think intermediate routers will have to interpret flow labels
as magic cookies. Maybe changing them (I have no strong opinion about this),
maybe internally sorting them according to a flow label - address/protocol/port
mapping for unencrypted packets; but as protocol designers, we can't enforce
a static mapping, else we would make hiding of flow properties through ESP
impossible to the users.
