Orson, That's a good idea, and I am actively investigating that. Check out https://kicad.github.io - currently only symbols and footprints are there but models are on their way. The scripts that generate that data use a very heavy 7z compression.
However, is this a reason to *not* add the array functionality provided in this patch? I still think it is a useful feature.
