Until we have a clear criteria for commits after delete, I'll use this: 1. lineal versioning (no branching) 2. "deleted" compositions can be "undeleted" using "modification" change type, since we don't have an "undelete" change type 3. if current latest version is "deleted" the composition won't appear on query results
