KDE doesn't maintain a fork or patch collection for XWayland, so I don't
think there is any way we can integrate that work ourselves. That would
be something for distros to consider.
You could also add your (polite) opinion to the comment thread over
there to show support for the proposed approach.

you’ll see that the programming has already been done (and isn’t even
very difficult from what I understand) – the problem is that the
upstream, well Gnome, developers have a seemingly ideological opposition
to this patch. They basically claim that any non-Wayland native
application should be assumed to have no support for HiDPI, which is
plainly false. Of the few remaining applications that have no support
for HiDPI scaling at all, it would not be difficult to force upscaling
with a GUI context menu or environment variable.
Windows can already do this:
My request would be for the KDE team to merge the aforementioned patch
for XWayland in Kwin/KDE. The changes are quite small and shouldn’t be
too difficult to maintain. I think the benefits are very clear.

Hello Alex,
Please feel free to help get these issues fixed upstream, as it seems
like you already have a good grasp of the technical issues at play.

The current status of XWayland applications in both Gnome and KDE
Wayland implementations leaves something to be desired, especially
with regards to HiDPI scaling. Currently, all XWayland clients are
upscaled by the compositor, which produces horribly blurry results
for many popular applications like Jetbrains IDEs, any Wine/Proton
game, and some common Electron apps like Discord and Teams. Those
same programs are able to scale just fine on a straight X session.
There is already an AUR package that contains the necessary patches
for XWayland on Sway:
https://aur.archlinux.org/packages/sway-hidpi-git/ Indeed a similar
fix was implemented two years ago in this merge request:
https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/111
Until this situation is fixed, the KDE Wayland session is not usable
for me, and I would not be able to recommend running a Wayland
session to a new Linux user. Because of this, I would have to tell
any potential user with a mixed DPI setup to stick with Windows or
Mac OS until these display issues get ironed out.
