Ordinary markdowns have had /everything/ you mention for close to 20 years, except typesetting. Academic papers and books, novels, thousands of ebooks, have been written in single file markdowns for 15 years.
Writing directly in typst is good for small things with intense typesetting like ... wedding invitations, advertisements. But it doesn't scale to serious composition by actual writers.
Writing is not typesetting.
All the forms need for the composition of all civilized text were present in word perfect 5.1, which unlike Word, Latex and Typst, permitted no typsetting during the process of writing. They were all recovered in the writers' markdowns nearly two decades ago.
So LaTeX also doesn't scale to serious composition by actual writers?

Huh? I roll to doubt. How do you do this stuff with markdown? I tried for ages but only got half-baked hacky "markdown extensions" which weren't even commonmark compliant. I've found nothing even remotely as powerful as typst in the markdown world.
I'm not sure what you mean. Markdown compared to typst or latex is extremely limited and using it for books or academic papers is very niche. I certainly would (and have for all my previous publications) prefer typst or latex over markdown. I also don't understand your point about not permitting typesetting during writing. Latex and text are the prime examples of separating writing from typesetting.
