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.
Ah yes. I used to have a GTX 1060 and was pretty pissed off when they said the new open source driver would only support from 1660 onwards (or is it 1630)...
