Right. the way I've been thinking about that is that traditional Flows, ala NSIS/RSVP where a flow setup protocol is in use, does still require uniqueness. But other uses of the Flow Label outside of that do not have that requirement. So, if you do traditional flows, you have to be sure to generate Flow Labels carefully. The default usage outside of signaling does not have the same requirement.
