Appears to "just werk" with Wayland, Debian 13, secure boot.

I get that the warnings are there there to showcase a "known good" configuration, but on Debian 13:
1. The deb package seems do the process of enrolling a MOK for signing the kernel module itself
2. KDE + Wayland "just werked"

So the warnings about needing to disable SecureBoot and using X11 seem to be obsolete
