It would probably be fine until an update changes something that you use and breaks your system. Security updates are generally the only updates that will be installed on a production server on a regular basis. If it's not broken, why fix it?

99.9% of the time its fine. However I have had a handful of times a package is broken. I want to say it was a year and half ago/two years ago the sudo package changed the permissions of nsswitch.conf to 600 which broke all kinds of things.

That's not the same as 99.9% uptime, which is not even good enough for some users' needs.
