We’re generally fine with people posting solutions to issues they’re having, so I think a guide about how to install Xfce on Kicksecure would probably be welcome (assuming it doesn’t direct the user to do things that are unsafe from a security perspective).
Maintaining an official Xfce variant of Kicksecure is probably a lot of work. It would involve the introduction of as many as ten new images (Kicksecure VirtualBox Xfce, Kicksecure KVM Xfce, Kicksecure ISO Xfce, Whonix-Workstation VirtualBox Xfce, Whonix-Gateway VirtualBox Xfce, Whonix-Workstation KVM Xfce, Whonix-Gateway VirtualBox Xfce, Kicksecure Qubes Xfce, Whonix-Workstation Qubes Xfce, Whonix-Gateway Qubes Xfce) that would have to be officially supported, along with the metapackages for them. The maintenance burden would have to be something a community member was willing and able to maintain themselves, and if they stopped maintaining it, it would likely become deprecated and removed very quickly due to the scale of work it would entail. (I’m not sure if we would accept it at all due to how much work it would add, but that isn’t my decision.) Additionally, the experimental Wayland support in Xfce is missing many important things in Debian 13 that were, in our research, even worse than the things LXQt was missing. See:
