Syntax suggestion - drop the need for "= null" on nullable properties (that have no initial value)

Can you, please, share some more details about partial rendering in serialization thread here: Kotlin Serialization - #21 by mikehearn
We are still very early with it to say that we have or don’t have any plans with respect to any specific feature of serailzation. The more use-cases we gather, the better we’ll be able to support them. P.S.: right now I am prototyping interface serialization that could be used for some instances of partial rendering like jackson views, but I don’t know if that is going to cover your specific use-cases or not.
