How can this flaw be an intended design of a blank partition?

[PommeDeTerre]

The way I see it: There is design and there is functionality (i.e. perks) in an FC house. All members should have access to the perks (stables, summoning and crystal bell, mender, material vendor, FC buffs, etc.) but they should not have access to the design part (wall designs on blank partitions, aquarium fishes, paintings, etc...), unless of course these rights are given to them. Design and functionality are partly overlapping atm and they shouldn't be. They should be 2 separate things.
