Inline NamespaceStorageSupport.accessNamespaces()
We have multiple callers, but all of duplicate the functionality
of getLocalNamespace(). Inline accessNamespaces() into
getLocalNamespace() and adjust users to use that instead duplicating its
code.
This removes a the need for a number of warning suppressions and makes
it clearer as to what is going on.
