For example, I'm using Debian, and I think we could learn a thing or two from Mint about how to make it "friendlier" for new users. I often see Mint recommended to new users, but rarely Debian, which has a goal to be "the universal operating system".
I also think we could learn website design from.. looks at notes ..everyone else.
What I really like about stuff like RedoxOS, COSMIC, typst, simpleX, Wayland and others is having stuff built from a modern perspective with modern practices.
Linux is ancient now, and its a miracle that it is thriving like this.
If dynamic loading really is that robust, it probably doesnt matter. But I dont know how big the performance increases are and I really need to do benchmarks before and after.
There are btw also some experiments on making tbe CentOS-Stream LTS kernel run on Fedora. Which would be another great way of getting a more stable system.
