Objects that declare all their members in the constructors tend to optimize better. They also have a much clearer intent of what we are trying to represent here - logically speaking this is not a dictionary though clearly a dictionary could be used as one way to implement it. They also make it easier to add methods later - this might be slightly controversial but given a bunch of people want it, seems like we should at least keep that future door open for now.  If we were using any language other than JS which blurs the distinction between objects and dictionaries, we would not even be having this discussions and would have just declared a class or extensible structure for this. 

Is there any concrete argument for dictionary over object for the thing that holds the SDP? 

I normally don't care too much about the things like this that only change the syntax and not the semantics of what is possible. But one way or another, I'd like to wrap up this thread and move forward.
