As mentioned in the ObservableCollections Issue, it is not convenient to use ObservableCollections.R3 as a replacement for UniRx.ReactiveDictionary.
I consider ReactiveDictionary (and ReactiveCollection) to be used frequently, so it would be helpful if you could include this in R3. (I would also request a Readonly version and the ability to issue OnCompleted at the same time.)
