Windows has it's own implementation of containers, and with a docker-like structure, and xlsx being a zip file, excel could simply have a dockerfile like structure "FROM excel-python:2023" "COPY xlsx:scripts/" etc. new versions of excel could keep the last few 'base' containers, or if they are in love with the cloud, the signed, verified base images could be pulled on request.
