This deletes the entire history of these metrics. Are we sure that's what we want to do? If so, are we able to backfill and rebuild the history?

This seems like it's definitely :badvibes: I should've caught.

But how should we handle the old data? Just leave it be and show a drop in TBL? Backfill using a different approach?
