I'm sorry, what exactly is the issue with typst?

No issues per se, but academic publishing has deep roots in the latex ecosystem. So templates from publishers are often not available in typst, or the publisher insists on a latex formatted file.

Often supervisors/professors etc will also resist using typst because of the cognitive overhead on their already oversubscribed time. Typst has about 40 years of history to overcome and that will take a long time to do.
