 * the first backend on the list and whatever happens, happens (NO_DATA etc).
 *
 * For all other services available on the top-level backend API, the composite backend delegates to the first backend
 * on the list.
 *
 * Note on backend capabilities: the composite backend will inherit capabilities from the first backend component. It
 * will not do any other processing in regards to capabilities. This can potentially be limiting and breaking in
 * situations when the backend is composed from multiple different implementations, each with different capabilities.
