* of {@code null} variable values is not well established by the GraphQL specification. It
* states that:

* null may be interpreted differently
*
* while also stating:
*
* The same two methods of representing the lack of a value are possible via variables by
* either providing the a variable value as null and not providing a variable value at all.

* See https://spec.graphql.org/October2016/#sec-Null-Value.
*
* Note, the default setting is {@code false}, which does not remove {@code null} variable/input values.
