No that doesn't solve the clone/fetch of large amount of data cleanly.

This is an idea to consider independently of any other issues.

No.  Larger pack files are not more expensive than the same set of 
objects spread into multiple packs.  In fact I'd say it's quite the 
opposite.  And larger pack files do not require a pack format change -- 
it's just the index that has to change and the index is a local matter.
