Yes I am involved in the project. As for not worrying about large system upgrades, things break, no matter how much testing you do on them. For running KDE I prefer to run the latest, it has the least bugs and the newest features.
There will be at minimum 3 editions of this OS, one for developers and those who love to live on the bleeding edge, one for enthusiasts and one for general users. The one for general users will be well tested and aim to have zero showstopping bugs.
In other words, they don’t have enough resources dedicated to doing it well.
No they’re resourced quite fine, trying to mash old with new is never going to smooth.
That could reduce the work required in one area, but increase it in another. Arch fails the “doesn’t break” goal on its own, which means someone would have to do more work to achieve it.
And that’s why they have each release as it’s own btrfs subvolume, if it breaks, you roll back, done. There will be 3 (maybe 4) variants and users will be encouraged to run the “stable” variant which is managed as a snapshot in time deployment where KDE Linux and KDE devs together agree that the system is stable and has 0 critical/showstopper bugs.
