You are claiming that is a one year old issue in the grpc-go project.

But we are not seeing any change in that code (https://github.com/grpc/grpc-go/blob/master/server.go#L228) in the following releases. And I tried to look for an issue mentionning MaxMsgSize and found nothing. https://github.com/grpc/grpc-go/issues?utf8=%E2%9C%93&q=MaxM...

The fix that would restore the compatibility you claim seems obvious:

  	func MaxMsgSize(m int) ServerOption {
  		return func(o *options) {
  			o.maxSendMessageSize = m
  			o.maxReceiveMessageSize = m
  		}
  	}

This fix could have been applied in a minor release to restore compatibility without breaking the API.

So if this is an issue, why is this not reported?
