I thought the use case in section 9.6 was pretty clear -- "This is particularly useful when clients initially connect to an address shared by multiple servers but [the server] would prefer to use a unicast address to ensure connection stability".

Migrating to a unicast address avoids having to perform connection-based routing through a load balancer.
