This is not something that is on the team's current plans for the foreseeable future.

@dfawley : Do you know if C/Java have this support or they have plans for this? Thanks.

Along with grpc/grpc-java#8897, let's close this in favor of the cross-language issue at grpc/grpc#19126.

Ok, I will move my arguments/request to the 'cross-language' thread.
