While Nintendo has not provided any reason why these changes will be made, it is stated that the discontinuation will not affect Super Mario Maker 2 for the Nintendo Switch. However, the Wii U version may not be as popular as its Switch counterpart and Nintendo feels that supporting both versions is too expensive.
