      Our new upgrade/downgrade policy means that once users upgrade their FCV, they will not be able to do a binary downgrade without the help of the support team. This could cause a lot of distress for customers who won't realize that they cannot downgrade on their own until it's too late.

      The setFCV command will now require an extra parameter

      {confirm: true}

      to do an FCV upgrade/downgrade. Without that parameter, the setFCV downgrade command will error and say that an FCV + binary downgrade will require support assistance, and to re-run the setFCV downgrade command with the confirm parameter if you acknowledge that. The setFCV upgrade command will error and say that once you have upgraded to <targetFCV>, FCV + binary downgrade will not be possible without support assistance, and to re-run the setFCV upgrade command with the confirm parameter if you acknowledge that risk.
