Feature: System.Text.Json

Is there work in progress to move to System.Text.Json.Serialization? Not asking create this serialization option feature, as it would be a major change. But curious if it has been considered or is in the works. Was thinking about taking a try at it.

As a featurish question, feel free to close at any time (no response necessary. especially if you don't have the time).

Thanks for the great library! Visual Studio built-in support works great, even for Azure Functions calling other Azure Functions.
