You are assuming everybody does initial clone all the time.  I
do not think that holds true in practice.

For something like tglx historical tree that will _never_
change, there is a specific hack the repository owner can take
advantage of to always feed a prepackaged pack, although its use
is not advertised well enough (and I do not think it buys much
in practice).
