Unless I'm mis-reading something - I believe this packing would only
apply to "closed" shards. That is, content that will not change (and
this might need to be enforced? prevent revprops in a packed shard from
being updated?).

For hard linking - which I found doubtful as a good backup solution
(changes to the original file also change the backup file - so it's not
really a backup?), why couldn't you hard link the packed file?
