Description

Allow unused types for all dictionary types, rather than restricting to just ObjectTypeDefinitions. This allows unused enums, interfaces, unions, etc.

Use Cases

We use a combination of missing field resolver, and unused types to allow preview fields in our schema. E.g. schema without resolver implementations. We achieve this with a mixture of using the missing field resolver option, and generating empty types to be registered by SchemaParser.dictionary(...).
