   I think (1) and (2) from above are pretty straightforward. With (3) I think it makes the Python worker a bit better now that `StructType` can be returned from a scalar udf, but it does require the struct to be flattened out in Scala, so I don't feel too strongly about pushing this in. Please take a look @HyukjinKwon @ueshin @icexelloss and let me know what you think, thanks!
