CS strongly prefers LaTeX [0,1] while broader journals and conferences prefer MS Word over it [2,3]. As long as there is not a solid infrastructure for these other typesetting systems, I never saw the appeal. I think for internal company reports they do have their uses, but other than that, why not use the LaTeX or Word? Realistically any person wanting to submit a work will know how to work with either one or the other.
I also don't see the need for journals and conferences to make a typst template for exactly these reasons. The templates will have to be community-made and then you still run the risk of having a paper rejected a year from now because the template is outdated.
