The issue with that is potentially keeping software which has security bugs on your system for longer than needed. Also, if you install new software you’ll have a partial upgrade which can degrade your system. If you don’t install anything though, your system should work as it currently does without issue. Unless a particular app takes something from the internet which may need the upgraded software (say, discord, spotify, etc. as they’re electron based.)
If that’s what you want to do I would suggest switching to xubuntu, mint xfce edition, DSL, etc. as they’ll still patch security updates in. You do you though of course as with your stated usecase I can’t see any functional issue. I don’t see the reason for arch though.
Rebecca black Linux is for the real men though.
Most forward thinking distro. First to ship with Wayland by default and the only of the three still getting constant updates.
No competitor really. It’s always Friday Friday, gotta boot up on Friday with rbos my friends
