I may be missing something here.
My understanding is that, if using a singleton, toJS(XX::create()) will always return the same JSXX object. This is not what we want, we want a new object each time. 
Hence why I think we should bypass the cache and remove the generation of the toJS(XX) function. Once done, the singleton class might be made private to the JS class or applicable to all classes.

I agree, that is the idea behind removing toJS, releaseImpl and so on...
I haven't done the exercise so cannot comment on how much complexity it will add to the binding generator.

You are probably right about the limited complexity it will need.
But the binding generator seems already a bit messy to me.

Do not hesitate to move that forward directly.
