To be fair, if every install of Excel started installing a full docker container of Python, anaconda, scikit, statsmodels, pandas, Matplotlib, seaborn, and more people would complain Excel is far too bloated. They probably could make it an optional local install, but it sounds like focused on UX first and wanted collaborators on Teams to have the same experience which would maybe be harder with mixed local installs and cloud containers.
