There was a problem hiding this comment.
I don't think we really support all under a Struct. We don't support maps under a struct and we don't support UDTs under a struct. Could we be more explicit about what we do and do not support here?

Depends on rapidsai/cudf#14309
This PR re-enables
from_json/JsonToStructs. It was previously disabled (see #8558) because it can cause incorrect results in some cases, but we have similar issues when reading directly from JSON files (see xfailed cases in #9304).Given that this expression does work correctly in many cases where the inputs are valid JSON, and that it is disabled by default, I would like to discuss adding this back in.
