This is a small preprocessor for graphql-go schema structures. Given a schema, it can systematically remove or modify definitions. It's used primarily via a single function:
func PreprocessSchemaConfig(input graphql.SchemaConfig, config *PreprocessorConfig) graphql.SchemaConfigPreprocessorConfig has a single field: BetaFeaturesEnabled. If this field is set to false, the preprocessor will intelligently filter out types marked as "beta" by the Beta function (and their dependents), making feature toggles trivial to maintain.
