Not as helpful as one might hope! :( But it does make my job somewhat less tricky :)
May I suggest a method by which something like this is possible. Perhaps an additional 'field' on the admin screen allowing one to add a 'fieldname' property. This fieldname property could be sent with the form submission, allowing capture to map fieldname with input field name (or 'field id' as you call it).
Using my example above, the data would be a bit like:
GFfieldname_input_1 = 'newspaper'
input_1_1 = 'daily blag'
input_1_3 = 'weekly blag'
GFfieldname_input_2 = 'hidden-date'
input_2 = 'YYYY/MM/DD'
Event better, as it is a WP plugin, you could add the GFfieldname properties in using apply_filter on the results, and in turn allow theme/plugin builders to hook into that for 'form capture', rather than rely on parsing $_POST ?
