I don't see how that will help. The block group IDs (which is all that we get at this level) are effectively arbitrary 64-bit numbers, and are what appear in the kernel logs. How could that information be used to improve monitoring? I'm not ruling out the idea completely -- I just can't see at the moment how it would be used.
