As a KDE user since the last millennium, I love the work they are putting in.
But I was burned by the KDE3 -> KDE4 transition. And then the KDE4 -> KDE5 transition.
So I've parked on Debian bookworm for the next couple of years while KDE 6 gets ready. If it's good to go in 2 years when Debian trixie is released, great!
But if it's still a mess of Qt5 and Qt6 libs and still waiting for feature parity, I can stay on bookworm and still have a reasonably stable desktop until forky.
