PS5: 
who is going to continually update the config file URL so that new boards are supported?

the last thing I want to do when I need to pull down a recovery image quickly for a new board is to have to check archive.org to try and figure out when support was added / update the URL/checksum.

effort would be better spent fixing the shellball extraction for newer boards which contain multiple firmware images IMO
