Building a python environment with python3Minimal requires hydra to bootstrap pip and build all packages used in the environment which would otherwise not be built. This reduces cache re-use and duplicates things. Also common dependencies normally included in python itself are not properly checked and can cause hard to debug errors because everyone just assumes those modules are there.
