This is awesome and has so much potential!

Regarding the size of the download, I know there is ongoing work in the Pyodide project to create a much smaller python runtime that will help tremendously. Also, the script will be cached once you download it once.

EDIT: Also, you don't need NPM or anything locally to run these

Adding -Os to the Pyodide compilation flags has proven surprisingly hard: https://github.com/pyodide/pyodide/pull/1882

But some other low hanging fruit include unvendoring the special encodings for Asian languages (hopefully everyone uses utf8), the decimal library, and the xml library which are all quite large and only occasionally used.
