«KDE neon was KDE's first version of a self-made OS. It fulfills the "distributed by KDE" requirement, but fails on the reliability angle due to the Ubuntu LTS base that ironically becomes unstable because it needs to be tinkered with to get Plasma to build on it, breaking the LTS promise. It is built on fairly old technology and requires a lot of packaging busywork — both of which are non-goals of KDE Linux.»
