What are the "Additional Software for Selected Environment" options?

I was trying to install Qubes 4.3.0 and noticed some options listed under “Additional Software for Selected Environment” in Software Selection. The options and their descriptions are:

  • Qubes UI (Audio/Gui)
    • Qubes UI daemons
  • Desktop accessibility
    • This group contains essential accessibility stack to be used with desktop environments.
  • Sway Window Manager (supplemental packages)
    • Sway is a tiling window manager supporting Wayland compositor protocol and i3-compatible configuration. This group includes additional set of packages for Fedora Sway spin.

The Qubes UI option is selected by default.

I would just like to know what exactly these options are and why I would or would not select any of them. Maybe I overlooked something, but I didn’t see any mention of them in the installation guide and haven’t been able to find mention of them elsewhere yet.

If I had to hazard a guess, I’d assume the Qubes UI option is necessary for sys-audio and sys-gui? I also saw that Wayland work has begun, but I haven’t seen anything mentioning sway being an option, so I’m not too certain what that option is for. And I’m not sure what the Desktop accessibility offers.

Sway does not work yet, it shouldn’t have landed in the 4.3 installer.
