Yes, we plan to have top-tier specific memory protection (like memory.low) and memory limit (like memory.high).

Both promotion and demotion/reclaim path. If we want top-tier memory protection and limit, moderating both promotion and demotion is I think a must for converging on a stable distribution of memory usage on top-tier and slower tier. Kaiyang
