For me, being able to open typical .doc files and re-save as .md w/ a reasonable approximation of formatting is _huge_, and I'm very appreciative of it (and I've long argued that an office suite which just offered only what .md can do would meet the needs of the vast majority of users _and_ keep them from making the sorts of abominable documents folks often complain about).
Pandoc could convert between .doc/.docx and .md, but having that in LibreOffice would still be a welcome and obvious convenience.
It’s interesting, a lot of use cases have migrated to tools like that, including Apple Notes, Notion, Slack Canvas and, of course, Gmail and Outlook.
I think a lot of people “need” Word the same way they “need” a pickup truck. It feels better to buy it up front than to worry about needing it on short notice and not having it.
