In the light of extending our eKMS support it will be helpful to have a tighter use of the word "KMS". KMS should refer to the actual component that manages keys. The keyservice, also called KMS in the constellation code, does not manage keys itself. It talks to a KMS backend, which in turn does the actual key management.
