No more superficial than a Tomb ?:-D
Star Wars isn't reality. It's fable and ripe with symbolism.
The notion of a significant object starting out as a shining royal yacht, changing form and becoming a pirate ship but still fighting the good fight is in-keeping with that milieu in my view, though clearly not in yours.
The Falcon isn't just a ship. She's as much a character as the Tardis or the Enterprise or Trigger.
