An unexpected 304 to an unconditional policy-limits request is now a hard failure, and the 404 fast path was removed.
An unconditional (non-etag) request to the policy-limits endpoint that unexpectedly receives a 304 Not Modified response is now treated as a hard failure instead of being accepted as valid cached data. The 404 'no restrictions found' fast path has also been removed from this handler.
