 Description   

We're brainstorming some approaches in https://docs.google.com/document/d/18-HnOeQQUnQSRXxmsZkB-m4g5CcxHep7vixlJiHDmDw/edit. This ticket tracks the work to review that, flesh it out, and generally comment.

With the spike wrapping up, it's not clear if this ticket should remain open and active while we have the context, or go into "hibernation" for a while before we get to the next proposed spike to investigate stats and histograms more. For now, I'll just remove it from the epic while I wait for feedback from our European colleagues.
