About structs having no members

If we call MakeStruct of a struct not having any members, a warning message, “@@ has no property tagged as BlueprintReadWrite. The node will be removed in a future release.” is printed.

I’m using many empty structs for requesting packets. I want these structs to remain in a future release, and also I don’t want to see this warning message.

Is there a solution without adding a dummy member or commenting codes of printing the warning message in Engine?
