What are the "so many better alternatives"? Google Docs is pretty decent but a fair bit more basic. Proper technical authoring systems like Typst, LyX and LaTeX are way too hard for the average person. LibreOffice is much worse than MS Word.
I mean workflows. Gdocs is disastrous in many scenarios. I think document management should be more like software version management with a nice ui. Editing the content (what it has) vs editing the template (how it looks). Markdown + a typst template gets you far. I have exactly that for my docs and it works very well. Not sure yet about how a decent size company could adopt anything like that.
