This form component is very flexible in how it manages field names for you, especially while developing a form as you can add or remove field names (components) at will without any fuss. However, it only keeps adding names and never removes them. Presumably because there may be existing data in the DB associated with a field name you've deprecated. However, typically with us at the end of a long form development cycle there will be several deprecated fields and before you go into production it would sure be nice to remove all of those deprecated items but sadly you can't. Even if you clear all the submissions the deprecated field names are still present, which is technically deficient. Clearing all submissions should definitely clear all the field names.
