   I generally agree with the first two points, although I do like the explicitness of a leading dot.
   
   The third point, it could be a potentially buggy convenience add on. ie.
   ```python
   pa.table({"a.dotted.field": [1], "nested": [{"field": "value"]})
   (..., columns=["a.dotted.field", "nested.field"])
   ```
   vs explicitly mapping maybe?
   ```python
   (..., columns=[{"my_dotted_field": "a.dotted.field", "nested_field": "nested.field"}])
   ```
