There’s definitely a weird crossover point where furniture items are so simple that you could re-create them in seconds with canvas primitives. However, it’s nice to have prefabs for players who might not be familiar with advanced building techniques or don’t have the patience to make everything out of primitives, even if it’s technically possible. I don’t mind more plaza furniture items being added even if they’re simple. Especially if they’re already in the game - it’s good to reuse game assets where possible.
