We might have to wait even longer for all the common law based on the court rulings to be published in the same format. Not to mention the "secret common law" based on the FISA court rulings.
Not sure what format the files are kept in, but it's been done. Several private companies have these behind a paywall:ThompsonWest and Lexis/Nexis are the most well known, but there are others. Don't forget the published caselaw of the fifty states as well as state legislation. The U.S. Code is far from the whole picture.
