Exception thrown when deserializing interfaces

[Kokujou]

I'm trying to use models from Graph as DTOs, which almost works well until you have a look at some of the base properties...

I don't even need those properties, but now i get generated code like

    static fromJS(data: any, _mappings?: any): IBackingStore | null {
        data = typeof data === 'object' ? data : {};
        throw new Error("The abstract class 'IBackingStore' cannot be instantiated.");
    }

I get the problem partially, but it's blocking me so much, that i'd need to change the whole structure of my project so i want to either:

1. make them go away and just serialize to any or so,
2. delete all properties with interface types also from serialization/deserialization

if there'd be any generic solution that'd be nice.
