   There's the `pyarrow.compute.struct_field` kernel which can do these sorts of things for nested structs, but that is much lower level than what you're after here
   
   I'm not quite sure casting is the right name to give this operation, but I think there is room to add an operation like what you're proposing (whether it's called casting or not)
