Add metadata/omap to telemetry?

Hi, since the discussion "how big should my DB device be" comes up quite often: would it be possible to add (sum(omap) + sum(meta)) / sum(data) to the telemetry module? And probably some filter to only run it on clusters that are actually in real use? Because it starts out with 1 GB per OSD allocated. So maybe only do this if data / osds > 100GB? Or just subtract 1 GB from meta? Background is that the current recommendation in the docs (4-10%) doesn't match up with my experience (~0.1% - ~2%) at all.
