Caught by @tomek. `useStaffCanSee` is basically the same as `useIsRestoreFlowEnabled` anyway but because we were not using `useIsRestoreFlowEnabled` the functionality could still be turned off., but because we were not using `useIsRestoreFlowEnabled,` the migration could still be turned off after release.
This is because this handlesr was implemented a lot earlier than `useIsRestoreFlowEnabled`.
