@hj @mischievoustomato @novenary @icedquinn @wolf480pl Try it, I'm pretty sure it doesn't works and actually supporting it would be horribly annoying.

Specially because graceful degradation isn't much of a thing in JavaScript, which is why horrors like babel and core-js exists, but stuff still falls through the cracks once in a while.

And that's for the web, where things like ABI issues simply do not exist (except maybe with WASM) and you can quite nicely query for an API existence, which pretty much doesn't exists in other ecosystems.
