It's interesting they're changing the pitch from "everyday user" to "KDE enthusiast."
I definitely daily drove it for several years, and we even used it as our defacto developer distro at a previous job. It didn't seem to be too bad for that purpose.
Maybe not, but it sure feels bait-and-switch-esque. I suppose if that's really what KDE Neon has morphed into/is targeting now, it's better to be honest.
Nate's blog has been really encouraging people to submit bug reports. So I think the goal of Neon is to have the bleeding edge KDE with a stable base, to rule out confounding factors as much as possible. I don't think it's a bait-and-switch since the product hasn't changed. They'd probably just really rather it be used for people willing to submit bug reports.
