This looks like an interesting project, coming from another minority language - Raku - I can see how dogfooding like this is a great way to try and help Julia break into the Python hegemony (yawn) esp. in academic circles. otoh, I am not sure that a pure play Julia notebook thing is long run better than a pure play Python thing (Jupyter ofc).
Yet notebooks are a vital angle for any scripting language. So I guess I would like to see a language neutral notebook platform with pluggable kernels. Meantime Jupyter does that pretty well and, with Raku Inline::Python support for pip modules can be a lot of fun with a Raku kernel, especially with LLM chatbook use cases.
Jupyter is not a pure python thing, the Ju already stands for Julia, py for Python and the r for R

Doesn’t this already exist? .QMD files (Quarto Markdown) allow you to mix and match languages in code cells and is platform neutral. Python, R, Observable JS, Julia, bash, or any language with Jupyter kernel, all natively supported and you can easily toggle output between PDFs, HTML, etc.
