This is the original Creative world used by the new Chaotic United from MC 1.7.10 until 1.10. It was retired in favor of having a Creative world with larger plots. At first, the idea of 'Open Creative' was tried out - which was a Creative world with no plots at all, just a flat world. This didn't pan out, but the idea of allowing larger builds would be realized through expanding plot sizes to 200x200.
