As brought up by @syncer in Slack I share the same oppinion that there is no right to exist on service ssh allow-root.
Initially VyOS comes with a default user called vyos which has SSH access. Is there anybody out there who uses root for any work on VyOS device?
Beeing root all the time is bad practice. It's like walking with an open walled throug a strip mall.
I think it's time to remove this node. Please share your thoughts.
