It's called "World Building."
Agreed 100%
There are so many iconic set pieces / furniture pieces that are still waiting to get into the line, these little "wall with greeblie" playset designs would be the perfect place for Hasbro to slot in stuff like Echo Base computers, Death Star duty stations or conference room furniture, Cloud City dining room furniture, etc etc.
There is so much more that they can do once they've gotten their fill of alcohol bottles and pillows.
If the moisture vaporator accessory hadn't come out in 2007, I would still be advocating for that thing, it is one of my favorite "figures" they ever made!
