Why is it so hard to believe a "soft" door can't seal well against space if its engineered correctly? Layered, nonporous modern fabrics of carbon fiber and titanium could withstand the forces and it would only need a semi sturdy frame to house a seal system, which once under pressure won't move . Have you ever worked around pressure/vacuum components? It looks like an exterior cover anyway, probably a uv shield, not a door.
The guy in that video is an idiot. He claims ask the wiring is USB, but everything you can see is clearly screw in mil spec connectors.
