Approving because #1860 is already merged to main. My primary concern here is that the original commit on main doesn't actually describe when it is safe to use this setting and since this is a cherry picked commit, this doesn't either.

I am retracting this after reading the cndb-side comments, especially this one: https://github.com/riptano/cndb/pull/14772#issuecomment-3357605350
