Frankly, `getOrder` could probably be added later if needed (it could be added as a default implementation returning 0 or something).

So I agree `getOrder` might be helpful if exact ordering will be needed in the future, however, I guess we could skip adding `getOrder` this time and rely on `ServiceLoader` order
