I dunno. I’ve written a bit of LaTeX but does it really shine in this context? IMO the real advantage it has is that it can allow the user to express more complicated intents than Markdown (weird phrasing—my natural instinct was to call LaTeX more precise than Markdown, but Markdown is pretty precise for describing the type of file that it is good at…).

Anyway LLMs don’t have underlying intent so maybe it is fine to just let them express what they can in Markdown?
