I don't care about missing features, but I just want a way to export to latex using typst.

It's okay if this is not the day to day tool used to render, but this should be possible. It's just a compiler between two languages, and latex happens to be Turing complete (and can display arbitrary things to a PDF), so it's 100% in the "not impossible" category

With such a tool nobody has to know if you use typst personally. Just like, say, nobody has to know you use jj rather than git
