I mean, the same is true for Emacs. But that hasn't stopped other editors (e.g. VSCode) from developing large vibrant communities of users and tooling.
Not everything revolves around scientific journals and their archaic rules. For my team Typst was a perfect LaTeX replacement and we've been happy ever since we switched. It is easier to understand, has faster compile times and is more powerful without enabling shell escape. However, we're not in the business of writing scientific papers, we write technical reports for our customers. If it wasn't advertised as a LaTeX replacement, we might never have found out about it.
