@oblomov @smallcircles @django @ireneista You referenced the client-to-server (C2S) Delete. Did you intend to reference server-to-server Delete (section 7.4)? In either case, the Tombstone is optional (MAY). Removing the S2S cached representation is recommended (SHOULD), but not required (MUST) and the spec notes this behavior cannot be enforced anyway. In other words, not deleting a cached object when an S2S Delete is received is conformant, but not recommended without a good reason.
