An angle is that we allow for localized usage of the flow label as opposed to end-to-end. Another is that we allow for different semantics within a local domain, as long as the packet that leaves the local domain fits the requirements in RFC 6437. As you point out, it is worth noting that we include information about flow isolation and rules by which a flow will be routed, which is akin to Multi-Topology Routing though MTR is based on TOS bits. It would be good to design an architecture that encompasses such capabilities. We'll note that ISA100.11a is shipping with a flow label that contains an index to a state (so-called a contract) that is installed on the nodes on the way and by and large extends the notion of PHB on a per flow basis.
