Maybe I'm a bit anal but it really does just sound like what we already knew.
I've used KDE Neon for a while as a typical end user and it works solidly. You get the nice upgrade cadence for the kernel and software, but rolling release for the one thing I care about in my distro - the desktop!
I will say, that if they don't want to encourage people using KDE Neon as end users (I think it's just a disclaimer but whatever) I wouldn't ship it as the default distro for the KDE Slimbook; which is marketed at end users!
