I can think of one benefit of going through Wikileaks (or WaPo): there would be a review by experts of what is legal/responsible to share, redacting for example driver's license uploads.
One of the interesting things to come out in Dec 2020 is evidence that Wikileaks offered the State Department advance warning when the encryption keys for the Iraq War Logs were about to be published by their collaborators at the Guardian. Prior to that, publication of the Iraq War Logs had been piecemeal as they redacted PII.
