Those are tools you use to write, not typesetting. It's equivalent to wanting to code on paper or use a specific editor. Cognitive connection to tools is a real thing, and I know a number of authors who really can't form a mental connection with their writing if not using their tool of choice.
That doesn't mean it's normal for them only use a certain typewriter because of its typeface, insist a publisher use Garamond to typeset their book for publication, or refuse to write without a certain margin.
To bring it closer to programming, in collaborative writing especially (think manual writing at large corporations), nobody is insisting that everyone indents paragraphs their way because it's better. As long as there's consistency those matters are best left to the printer. When I was younger I knew a lot of technical writers who in fact really disliked the move to Word from traditional word processors, because they didn't want to be distracted by those things.
