I would love to see an option to alter what is being spawned throughout the game, bumper/black hole-wise. I'd imagine this like a new option called spawnables or something with the options none/plain, bumpers, black holes and both (with the last one being the default.) Code-wise this shouldn't be more difficult than an if-else or a case-statement so I hope to see this implemented. I even would be willing to write and implement this function myself if I'd have access to the code lol.
