Review Comment:
   Yes, we missed this in a review 🤦 Field-IDs are superior over name-mapping, 
for example: dropping a field, and then adding a new field with the same name 
is not supported by name-mapping because it re-uses the name. In the case of 
field-IDs, a new ID is assigned and it will look like a new column 👍
