podman system prune should also remove all networks. When we want to users to migrate to the new network stack we recommend to run podman system reset. However this did not remove networks and if there were still networks around we would continue to use cni since this was considered an old system. There is one exception for the default network. It should not be removed since this could cause other issues when it no longer exists. The network backend detection logic ignores the default network so this is fine.
