There aren’t even doors between sections. Airlocks are serious things, there is one or two for station for EVA. There are multiple hatches for docking spacecraft. One of the innovations of ISS is larger docking adapter with bulkhead that is removed after docking. Russian section still uses hatches. All of the cables go through the docking adapter or hatch which makes impossible to close door or quickly disconnect.
