For curiosity's sake, why are route bindings being done in the service provider? Does route:cache prevent them from working in the route files?

[nWidart]

@mikemand I had the same question too :D . It actually makes sense, once cached, laravel won't open those route files anymore, and thus we would lose the binding, causing 404's etc.

Thanks @huydang284 for sending on 3.0, will check it out soon.
