It would be interesting to see if Nota could solve one problem that TeX and LaTeX, while theoretically capable, don't really solve in practice. Namely, the ease of styling according to dumb external requirements. Just to give you several examples:

  * Very tight, but very loaded layouts like A0 conference posters
  * Apply a national standard, such as, for example, post-Soviet GOST documentation styling standards
  * All combinatorial explosion of bibliography styling requirements in different international traditions 
  * Make the documents look like a default style in so and so MS Word version
  * Precise positioning of one picture upon another, or text upon a picture for quickfixes in the papers
  * Be able to consciously tweak any of the above

The problem with tex universe solutions here is while technically all of the above is possible, in practice it requires some black magic far deeper than a lay person (even with a scientific degree) wishes to dive into.

Templates are one reason products like Notion took off: they simplify the product, and build community at the same time.
