The current Admin export feature allows you to select specific field dependencies and specific dependent picklists - however the XML exported contains ALL rather than the selected ones.
Ideally the export XML should only contain the selected items (as with other export moptions used) or remove the option to select specific ones and stop the selection at object level. (eg Export all Dependent Picklists for the Control Object).
The current behaviour is not documented to work this way and is confusing for an administrator who would expect the XML to contain the contents selected for export. It can also be dangerous as you might think you are only exporting a specific change but in fact you would be exporting all,
