Some methods currently support a single platform only, but we may be able to support multiple platforms. This patch prepares the option-structs for multi-platform support, but (for now) returning an error if multiple options are provided. We need a similar check on the daemon-side, but still need to check on the client, as older daemons will ignore multiple platforms, which may be unexpected.
