If you're compiling millions of documents, many with thousands of pages, you probably need something very universal. LaTeX is boring tech, off the shelf, ready to use. It might take some work to figure out the initial setup with regards to templating and everything else, but after that, you can be generally pretty content that it will handle most things you throw at it just fine.

LaTeX is notoriously bad at being boring tech. It has a lot of very rough edges, especially when it comes to longer documents.

		And yet this very post positions Typst as a potential alternative to LaTeX. In other words, LaTeX is still in the top position. Personally I think ConTeXt is a far superior tool, though its documentation is always trailing quite a distance behind its current capabilities.
