That said... if this is a shoddy attempt at a "gotcha" style question - Screen sharing and remote desktop are both supported.
Ex - for Gnome:
https://wiki.gnome.org/Projects/Mutter/RemoteDesktop
LibVNCServer for VNC support, FreeRDP for remote desktop protocol.
For KDE:
Which mostly just works as long as you have Pipewire and xdg-desktop-portal-kde installed (the base plasma-wayland session usually includes them)
This one is a bit less polished - some users still have problems with keyboard input, depending on the distro and other installed packages.
For Sway:
xdg-desktop-portal-wlr works just fine for screen sharing, and you can use https://github.com/any1/wayvnc for VNC access (including having a completely headless machine).
