It’s obvious, which means the obvious reason is cost. Vacuum panels have been used in refrigerators before, but it’s been cheaper to make refrigerators thicker than add vacuums inside the structure to meet governmental energy requirements. Compressor improvements and foam are going to start struggling to meet ever tightening requirements, so vacuum panels and structures could be a new measure to meet guidelines.
