Do you think it is sufficiently respectful of TeX/LaTeX?
As far as proponents go, I will echo the sentiments of many people who have actually used both TeX and Typst: I have been able to accomplish many things in Typst within an hour or two by writing my own Typst code, that in LaTeX I could only accomplish after several days by cargo-culting indecipherable gibberish from years-old forum posts. I freely admit Typst can't (yet) match LaTeX's long-tail package ecosystem, but it is much more pleasant to use and easier to reason about.
