Before this change, when the above backends created a new backend they didn't put it into the backend cache. This meant that rc commands acting on those backends did not work. This was fixed by making sure the backends use the backend cache. See: https://forum.rclone.org/t/rclone-rc-backend-command-not-working-as-expected/18834
