Plasma on Wayland is a late beta yes, because Wayland itself is a late beta. I'd not use Wayland, yet if I want to use KDE, and if I need to install Wayland, I'd use another desktop environment.
I never restart KDE on my system, unless I upgrade my kernel, and restart the whole system.
Yeah, see, the fine print kills it. It's a "rock solid"* desktop, it does everything I want.
* Unless you use large network mounts, as long as you drag icons one at a time, for a fixed screen resolution, doesn't apply to Wayland, only until the next major rewrite...
Actually no. Because of my career, I deployed KDE to some very resource limited thin clients and it worked pretty well.
Also I talk with people who use KDE, and report bugs I encounter, or encourage people to report bugs when people I talk encounters them.
I'm pretty beyond "It works in my machine, so PEBKAC" at this point. I think using Linux for 20 years and managing a large fleet for 15 years helped on that front a lot. :-)
Oh, a milion humble apologies, my liege, I was entirely unaware of your decades of experience. Surely machines work better under your touch, for they can see the twinkle of authority in your eye. I shall revise my erroneous configuration for surely my ability to hold it right is insufficient; indeed, my mastery of software has dwindled since the days when my patches were accepted in KDE 3.1 and I am truly at a loss when it comes to manipulating the advanced software of our days.
