Nit: This should be included by the header.

What if someone calls ReplaceProvider() multiple times, for different paths?

Will this overwrite any previously serialized settings blob? If so, each
StoreCachedDeviceSetting() call will overwrite the result of the previous call.

Added deserialization.
