I would implement this as follows:
Add some option to repo-add to generate a second list like above.
"repo-add --filelists" would generate extra.files.tar.gz or something
Then a pacman config option like so:
SyncFilelists = yes
And everything else should flow from there.
Integrating json and xml parsing into pacman just seems.... wrong
