A bit tangential to the main topic of the post. They mention that they are working on another optimizing compiler Ion which will replace the cranelift compiler (which is still in nightly) as the new compiler for WebAssembly.
They link the issue [1] tracking the change which also speaks about disabling cranelift.
To my knowledge cranelift was made for the purpose of compiling WebAssembly in Firefox, so I am not sure if I am missing something here (it's not yet production ready maybe). The Cranelift README[2] mentions that it will be a backend for IonMonkey.
I am a complete layman here so I am curious if someone here has a better understanding.
