At the moment, shorthand_fields don't have defaults defined in the schema. Thus, they are dumped with --skip-defaults flag.
Wherever possible, we can match the defaults with the new fields and skip them.

Points to remember:

• Old gateway versions use "translate_backwards" field with an object to get the new fields.
• New gateway versions (post 3.9) use "replaced_with" with an array to get the new fields.
