Doesn't really need to be readable when compiled into WebAssembly though that I'd a goal. In that scenario it should work like any language in that you can debug in its native form.
MSIL and Java bytecode are not that readable but I mentally lump WebAssembly in the same group (though I know it isn't quite that). I feel like the end goal will be closer aligned to byte code than JavaScript.
I still don't really see the argument. It can already be debugged in its native form. I'm not sure how making the final product less readable helps with that.
WebAssembly is primarily useful from a performance standpoint.
