Documents the specific issue.

Though I definitely agree that if possible (i.e. if other things obeying the
Cache::Cache API do something similar) an undef return should provoke at least
a log message, and if possible some form of trappable error in
Catalyst::Plugin::Cache (since that should become the best practice way to
do session storage over time).
