Anyone got KDE running with Guix System?

I'm currently installing Guix System, but just read in the manual that KDE isn't really available yet: https://guix.gnu.org/manual/en/html_node/Limitations.html

However, there are of course lots of KDE-related packages:

• https://packages.guix.gnu.org/search/?query=kde
• https://packages.guix.gnu.org/search/?query=plasma
• https://packages.guix.gnu.org/search/?query=qt

So... has anyone managed to get a decent integration of KDE and Plasma Desktop into Guix System (ideally with Wayland and SDDM [the successor of KDM])? Can you all share your KDE-related config.scm files?
