They typically make mountains out of minor gripes with Wayland while completely ignoring the huge gaping holes in X11 that made Wayland necessary to begin with. You cannot give normal users a DE that lets any random application have complete control over all of your desktop applications. Sure, it is fine to say, "I am not a normal user, so don't push Wayland on me until it fixes my gripes," but because the author is not a normal user, he should not be using distros intended for normal users. That's on him.
Adding a permission system was a huge improvement. Not actually bothering to implement useful features, even behind permission gates, is not an improvement.
What useful features aren't they bothering to implement? The author's complaint is about window positioning, but that is correctly a compositor feature, and his chosen compositor hasn't implemented it yet. https://bugs.kde.org/show_bug.cgi?id=15329
