That's true. But there's way more of Word that I'd rather do without. Comments and edits are complex in Word. There's no clear way to do the starting point - comment - edit - resolution flow that we're familiar with as pull requests or traditional document turns. Track Changes works as intended, but creates complex mismatches between the state of a document and the state of a document to which a comment referred. Versioning is difficult. Almost everyone does it with multiple copies. Clean and redline copies. And so on. I prepare and negotiate legal documents every day. That practice is almost entirely Word based. Most tech-savvy practitioners have a brief spree with features they discover and master---automatic numbering, cross-references, style separators, tables of contents, and so on. In time, we tend to work back to a lowest common denominator, for simplicity and ease of collaboration. The best way to prepare a transaction document is often to treat Word as much like a typewriter as possible. As a rule of thumb, if you can't safely export to RTF, someone will mangle your document at some point. It may be you.
