It would be more plausibly practical if GHC could now target wasm, but this announcement is actually about being able to run the compiler itself in the browser.
It can target wasm, the point of the post is that it’s now mature enough to be able to build itself for wasm and run in a browser.
This is a show case of the wasm backend
GHC is built with GHC lol
