For #2: I tried it, downloaded the large file and installed. Then on launch, it couldn't find any JupyterLab install from my Conda environments, and it asked me to find it. I just uninstalled. I'm not sure what it wants or how it interacts with my many Conda envs and it's too much hassle to try and sort that out right now.

Same here - I filed a bug. I've got Jupyter-lab running, I have a clean venv - but couldn't start jupyterlab_app - even when I manually told it where to find the module in my .venv.
