-This service centralizes the configuration items, but theoratically each service should "push" its items toward the configuration service.

-Practically, it's the other way round as it's easier to use this configuration service as the single source of truth. This is why configuration items key and domain are immutable : services may use hardcoded domain-key pairs. Therefore, only values can be updated.
