Generated typescript has no reference to deprecated service messages

[zerovox]

What happened?

I marked some fields with a deprecation message in a service api:

      getGraph:
        deprecated: since 2.0
        returns: GetGraphResponse
        ...

It generated the following typing:

getGraph(graphRid: string): Promise<IGetGraphResponse>;

What did you want to happen?

I expected this deprecation message to appear somewhere in the generated typescript, probably utilizing JSDoc deprecated annotation which is supported by all good IDEs:

/**
 * @deprecated since 2.0
 */ 
getGraph(graphRid: string): Promise<IGetGraphResponse>;
