Feature request:
Support System.Text.Json writers.
More details:
Currently NEST supports Json.Net serializers. Microsoft has added a Json library to .net core 3 and a nuget package for other frameworks.
Will it be possible to use custom writers that supports System.Text.Json with NEST - I know you made a great effort to remove the JSON.net dependency, I hope this is a step forward in that aspect...
