Is this still an active request? Copying over Digger over as submodule or even by source shouldn't be too difficult?
I would say no. We have so many links to it nowadays that it doesn't make sense, even if Github redirect things. I don't think it's fair to the author and sole contributor either, who has never been a bottleneck.
