I am the co-author of a very similar application (CoCalc for LaTeX) and our landing page https://cocalc.com/doc/latex-editor.html lists many of the reasons people use it. A number of the reasons apply also to JupyterLab LaTeX, or will soon. A quick summary: realtime collaboration, having the paper you're writing and the data you're computing in the same place, having a very high-resolution history of edits, using latex in course management, using a Chromebook or other lightweight client, and zero configuration support for PythonTex and R (knitr). Note that some of these reasons for using JupyterLab or CoCalc are things that https://www.overleaf.com/ doesn't provide.

Having your data and your reports all in one place seems like the big selling point and I see this as pretty exciting.

It's my understanding that JupyterLab doesn't support concurrent editing or version control, unless these are baked into this extension?

Coming soon - they just closed their concurrent editing ticket! :-). https://github.com/jupyterlab/jupyterlab/issues/5382#event-4...

Same here. It's the most painful limitation of Jupyter, in my experience.

May be you could host it like overleaf? Eliminates the need to install latex which can be quite space consuming.

Using texlive package manager plus a python auto-package installer wrapper for latexmk I was able to get my latex install down to a 300MB.
