Interesting. Reminds me of Typst (both implemented in Rust and replacing TeX to some degree) and Microtex.
After a bit of tinkering and understanding the idiosyncracies of Typst, the joy of having reliable, consistent, beautiful, data-driven resumes and cover letters is not measurable. It basically lifted any barrier to applications, while whatever I had before I had always considered a burden.
On top of that, I can add hiring process data directly to the yaml file to run further analysis.
Can LaTeX do this? Most probably, but the learning curve is the difference.
