no, any load balancing which needs to scale needs to be stateless, so
you don't want session based mechanisms handling this.
Server load balancing is often stateful, and even stateless SLB
usually includes transport info in the hash. Or so I learned while
working on RFC 7098. People who know also informed me that ECMP
sometimes (not always) uses transport info (see RFC 6438).
