I mean, the winds are pointing towards pipewire and Wayland being the future of Linux mainstreaming, but there's a reason X.org and pulseaudio are still usually included by default. We're gonna need a few more years to iron out all the issues. Shit, look at something like BTRFS. It's been out for a decade now, and more people still recommend ext4 because it can be buggy in some use cases.

I always switch to Xorg before launching a desktop environment. Wayland support still sucks for many apps. Xorg just works.

When you support four Linux desktops as I do in my home, you shoot for stability between the varying hardware. Xorg provides that while Wayland finds a way to bug out differently on each PC.

Like the article said, Plasma itself usually works fine with Wayland. It's the programs that bug out.
