Option to exclude reference link ID

[jackling-yx]

With the release of https://www.contentful.com/developers/changelog/#cross-space-references-support-for-graphql-api on June 25th, Contentful have started to include an interface, _Node, with the field _id for all content types.

Although they have said that it is an additive change, it may affect tooling and they also do not recommend this to be included or used in applications.

Would it be possible to include an option to exclude this field when running codegen?
