I am wondering if there is a way to determine whether a change has

via bindings, without having to manually observe all of the keys.
The only option is to use dependent keys in the destination object:

I thought perhaps I could just observe the dict, but I don't recall
whether
NSDictionary triggers notifications on element changes (or I am
just brain
farting here).
Given that bindings work with dictionaries, it's not clear why you
would think that they wouldn't?
You simply observe the relevant key.
No core data-based suggestions, please. It is not an option.
It's not clear why Core Data would be relevant here?
