I'm one of the leaders of the ICU4X project which is a Rust implementation of ECMA-402 aiming to back client-side solutions.

We hope to eventually back SpiderMonkey (Firefox JS engine) implementation with it, but we also want to target WASM and in result expose it as a polyfill for any browser to use.

I don't know if by the time ICU4X is 1.0 IE11 will still matter, but it may be possible to compile it to asm.js and run in IE11 maybe?
