Thanks! Now that xeus-python has stabilized a bit, splitting the huge kernel file into multiple small files easy to cache, performing better at startup, I would be in favor of replacing pyodide-kernel by jupyterlite-xeus-python in the docs. What do you think?

It can also now use a dev version of ipywidgets since you can now pip install stuffs in the emscripten environment. Allowing us to test ipywidgets directly in PRs without spawning binder.

Good point, we could indeed give jupyterlite-xeus-python another try, especially since now it's also a bit faster to start.

Out of curiosity I quickly compared the Pyodide and Xeus Python kernels locally and here are some numbers:

jupyterlite-pyodide-kernel==0.1.0

jupyterlite-xeus-python==0.9.2
