Author here: I didn't tested but it seems in NixOS you can exclude any of the included applications using the `environment.plasma6.excludePackages` option. I am not sure if this breaks anything though, and of course, this doesn't help if you don't already use NixOS.

Much appreciated for taking the time to leave this reply. NixOS has been on my list for while. In the void for now, and inclined to stay ;)
