While I appreciate these projects, I can't see any headway for something like this in our academic community. We have a very established ecosystem of LaTeX packages, styles and documents, some of which are more than 25 years old. Everyone knows it. Everyone collaborates with LaTeX. Knowledge is easy to pass on because it is well understood. Everyone knows (or are) the people who write the packages or maintain things behind the scenes. This is all quietly boiling away without a single thing on GitHub.
To move to Typst, we'd have to start again and build all that again, because I guarantee there's stuff you just can't do it in it. I mean I looked at the options for tikz. One publication we have has 520 tikz figures in it for example. And that's dead.
Sure but you have to take into account how easier it is to build these things in typst. It's like one year since the first public typst release and someone already built a very functional "TikZ" equivalent called CeTZ. Far from being as mature as TikZ but easier to extend yourself.
