I like LaTeX for the most part (I have had to use some weird hacks but usually once they are done they are stuck in a macro and turned ignorable).

But I think the main things it has going for it are that it: produces nice output, and all the journals accept it. Does there exist a tool that renders Typist to LaTeX? That could play nicely with the existing ecosystem.

Pandoc can convert LaTeX to Typst and back but probably only for simple snippets without any obscure packages. It’s not lossless.
