Presumably the goal if detecting this is so that the host can quickly
acquire the new configuration when it has moved to a new link.

Also, the DNA charter seems to acknowledge this as being part of what 
the group should do:
"The purpose of the DNA working group is to define
standards track and BCP documents that allow hosts
to detect their IP layer configuration and
connectivity status quickly, proposing some
optimization to the current specifications that
would allow a host to reconfigure its IPv6 layer
faster than today."
