I don't know what I was thinking when I read your original comment, but I thought you meant the ones that come in the tubes. Guess I was half asleep. The extra tabs on the corners sound like they might be for structural support so that they don't get crushed as much when shipping or so that the box they come in can be weaker. I know plenty of the ones with the basic glued design open up on their own when weight is put on it.
I'm assuming they want extra cushioning and don't want the complexity that would bring. Maybe there would be issues where they would fall into each other's pits and get stuck or smash into eggs beneath.
I heard somewhere more recently that they probably did it on purpose because they didn't know if the game would be stable using the different settings. Nintendo was known for quality back then so if the game crashed, even a bit more, they thought it would hurt their bottom line.
I remember when he played minecraft and made a redstone contraption to auto-feed villagers or something. He started by saying that he wasn't good at redstone and proceeds to show something so complex that I would have to follow a tutorial to make it.
