Semantic Nullability

[devon66h]

Hello, I am building with Netflix's DGS framework and am designing my schema's fields to be nullable by default for resiliency. If a call to resolve a field fails, the field can gracefully return null instead of propagating up the entire graph to the nearest nullable field.

This works well in error cases, but I still want a way to tell client's that the field should be semantically non-null. In other words, if there are no errors, the field should be non-null.

It seems there's been a lot of discussions about this across the GraphQL ecosystem recently. I came across this talk which outlines a new @semanticNonNull directive which tells clients this field is non-null, unless there are errors.

Has there been consideration for adding support for this directive? This would certainly help our project a lot.
