You'd lose a lot and I'm not sure what you gain So gaining java, ruby, R, python, etc support for the web are no gain ? But the added value of graalVM is far beyond that, it revolutionize programming by allowing true polyglotism.

In economic terms, it would mean making accesible to the web millions of libraries which have a human/hours development cost of hundreds of billions of dollars.

Graal is a better target for these runtimes than WASM is, true, but Python-on-Graal is still a terrible target for the web. Huge runtimes with large memory footprints and startup times don't make for a pleasant user experience.

Polygot support, as extremely cool as it is, would be even less of a revolution inside the browser than it has been natively.
