I'll go further and say they should 100% use version control. I understand why they don't right now, but accommodating that seems like a relatively obvious lay-up for Microsoft. They could open source a docx-diffing/merging git extension, integrate it into GitHub, and integrate GitHub into Word. I'd also add that Word could add first-class Markdown/.md support. Seems like a pretty natural direction to go in as AI-assisted drafting/editing becomes increasingly commonplace, and would further simplify the GitHub integration.
