Well such object references and also string handling (not first-class representation in asm.js/current-wasm either) is just a lot of pointer munging really --- realistically I don't see many of today's framework writers re-expressing their visions at that level, plus in the browser context you need them to be "safe pointers"/"references" managed carefully etc.. can of worms. wasm/asm.js' prime use cases are certainly in high loads of real-time numerical calculations, I'm not just talking games or shader-helpers (and sciency/other simulations whether in academia or commercial solutions) but also envisioning faster, neater in-browser apps evolving for all sorts of media (pics/vids/audio/360°/etc) handling/editing/munging etc.
