As a computer science researcher, I have hundreds of LaTeX macros, basically a DSL for my specific field of research, where I more or less write out natural language and it comes out as formulae with all the specific symbols and stuff.

I think for people who write LaTeX in this kind of professional capacity, the macro language is the killer feature.

But I could see fields light on formalism embracing something like this over Ms word, if there was a nice Toolchain for collaborative writing and versioning.

Writing LaTeX macros to do something useful is hard. While this particular new system has functions as native object.

Typst supports macros/functions, more pleasantly than Latex too!

That's a well hidden feature.
