My understanding is that the repacking with -a redoes the computation to repack ALL the objects in every pack and loose objects, whereas what would be preferred is to try to delta new objects (loose and packed) against the existing .keep pack (extending it with the new objects) but not trying to re-deltify objects in the .keep pack. This is because .keep files are primarily for those who are cloning onto a machine that isn't powerful (maybe even a laptop/palmtop) but who are cloning from a powerful server, so that you wouldn't necessarily want to apply your strategy unconditionally.
