confirming that this is _not_ possible to declaratively define this:
```extend type SomeTypeWithComplexKeys @typePolicy(keyFields: "fieldA complexField { id }")```

context we have some types with nested fields that are unique that we may want part of caching key. obvious solution is to ensure all types get an `ID` field, which we can do too. or use programmatic keys

Correct, this is not possible currently. Tracked here: <https://github.com/apollographql/apollo-kotlin/issues/5203|https://github.com/apollographql/apollo-kotlin/issues/5203>
