You can’t allow to lose sight of context. In general I agree with you, but this is not a production server or even a system exposed to the Internet. This is an internal server hosting my stuff to me and only accessible via a VPN server that is on a different machine that is updated regularly who in turn is behind secure physical network devices with their own rules. This machine only job was to be available when called upon and it always has been. It does not need a kernel update although it could use one. All software on it is up to date and all security patches are updated regularly. If by any chance the system was fully compromised, all the culprit would get are tertiary copies of my movies and music collections, which they can enjoy, and a bunch of tertiary copies of my VeraCrypt virtual drives in which I replicate my backups. Again, context.
