Thats quite the runway. That helps them focus the attention on Wayland specific issues to get it more up to speed with X11.

Plasma 6 Bugs
If you encounter a bug, proceed to https://bugs.kde.org/, check whether it has been reported.
If it hasn't, report it yourself.
PLEASE THINK CAREFULLY BEFORE POSTING HERE.
Developers do not look for reports on social media, so they will not see it and all it does is clutter up the feed.
Bad news
Was nice that they mentioned some of their terminal utilities for scripting/automation. I ported my own scripts over just before Plasma 6 released and haven't looked back. And having those utilities made my own move to Wayland a lot easier.
There are still occasional things I miss from X11, like Barrier for example, that made using a single mouse/keyboard across multiple systems work like you were just on an extended monitor. But my move was very smooth, and I'm sure it will only get easier between now and the actual end of X11 support.
It was inevitable, but my nVidia GTX770 stuck on the legacy 470 drivers is still very sad.
Hopefully by that point the nouvou driver will have good enough performance for Moonlight streaming (client-side)
Too soon, IMHO. This is going to be disruptive to people who rely on X11 functionality that's unsupported or broken on Wayland and XWayland.
I can only hope that the fallout leads the wayland-protocols maintainers to finally address more of their project's deficiencies.
Current Plasma is still aupported until 2032 or so, so there are still a few years to close the gaps.
Is there anything in particular that you miss?
Yes, but I don't want to dox myself here by pointing out specific issues that affect me, and I already have a plan to address my particular needs (although it will require significant work and still leave me with a worse Plasma experience).
I'm more concerned with the impact on the community as a whole. This will push some people into migrating to the ghetto of a very-long-term-support distribution, costing them time and making them second-class citizens, and is likely to push others into giving up Plasma entirely. I don't think we will hear from many of them, since most people either do not participate in software discourse on social media, or will realize that there's not much point in shouting when you've been deliberately left behind.
Most, like 95+% of users will never even realise. Hell, they didn't realise when we switched them over to Wayland by default in Plasma 6. Even less so now with NVIDIA at last getting their act together, and devs having spent many human-hours in figuring out support for graphic tablets and so on. And even less a year from now when we have full feature-parity with X11.
You may be underestimating the competency and speed of KDE devs. These people are an effing top.
Will there be people who still need X11 a year+ from now? Maybe, it will be for really niche reasons: very specific hardware (most most common tablets and drawing pads are already supported) or really old legacy software their company requires them to use.
Either way, there will be compatibility layers, distros and maybe even forks of Plasma with X11 support, so this is all a non-issue.
