I don’t think this analogy is correct because traffic lights are a tool that should be used by vehicles and pedestrians, and if it is not used, accidents are inevitable. Whereas in Tumbleweed it is recommended not to use a pre-installed tool (YaST Software or GNOME Software or Discover), because if you do, it will break the system one day. Telling casual users “don’t use any GUI, only zypper dup inside a Screen or Tmux or Teletype session.” is not a solution either. I want to repeat what I said in another thread: if no GUI is recommended for system upgrades to Tumbleweed, why do they exist?
