This is not correct. To the passengers, this just looks like another seat next to a window with a plug installed. It's not a door.
If there was a reconfiguration to a seating standard that required the extra exit, the plug would be removed and a proper door would be installed, with the associated interior pieces.

This is true.
However there's still common hardware in there to allow the plug to be installed and maintained. This is why it's a complicated set of kit vs just bolting in a permanent fixture.
