The main issue with this effort, on Wikimedia and
elsewhere, will be that
there is no guarantee we have any metadata about file attribution and
copyright status. See also

As that page shows, we have machine-readable metadata for the license at
least for 99% of Commons files and 99% of all files. The number probably
gets much higher when weighted by number of views. I would certainly not
consider missing metadata in 1% of our files the main issue.
