That started many official release builds ago, but at the first one it was because all sku's contained another, not identical winre.wim, adding 300+MB x the onboard sku's (not full AIO iso's like now). But you can compress the install.wim to install.esd or multiple install.swm files, simple tool: https://forums.mydigitallife.net/th...-install-esd-install-swm-creation-tool.78925/
