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?
