It is orthogonal in a sense, but consider something like the
following.  I set up a connection with a primary path and a secondary
path, using the same primary path for CM communication.  Some time
later the primary path fails, so APM causes the connection to migrate
to the secondary path.  I get a "path migrated" async event and so I
want to set up a new secondary path so that my connection remains
resilient.   Where do I send the LAP?
