All the implementation tasks have been moved to other epics:

• [Security Solution] Users can Customize Prebuilt Detection Rules: Milestone 4 #179907
• [Security Solution] Asynchronous Detections API endpoints #221305

We can close this one. Any new performance-related tasks related to prebuilt rules should either go to Milestone 4 (if short-term) or to the backlog / other epics (if long-term).
