Review comment:
Not sure that I agree that 'serializing everything as a JSON string' is
the right way forward. Nor do I think that we should forgo making our code
safer, cleaner and easier to use because an engine cant _directly_ handle it.
As @nastra pointed out this annotation generates the annotations and objects
that Trino needs to serialize (namely `@JsonCreator` and `@JsonProperty`.
