I mean, not every shiny version is a mere gimmick. Cura just added improved tree supports, which are a great quality of life improvement.
I will not deny that having a robust stable system will always be better than having every package the newest version.
I am ignoring size, which as much as it doesn't matter for my computer setup, is still space that can be better spent on games and video.
Damn, I guess I need to learn Nixos.
