Currently control measurements are stored in a separate obs_web_ctrl table, however this presents challenges when needing to do cross table joins, which are not very efficient in clickhouse.
We might want to store them inside of the obs_web tables, but in doing so we should verify that it doesn't lead to any other unexpected consequences and will work well when implementing analysis.
In the end it turns out this is no longer necessary, at least not for a first iteration of it in light of the new approach. I am going to close this issue as done.
