That does help in the case of cloning torvalds/linux.git from
kernel.org, and I'd love to see it used transparently.
However, even with that, I still also see value in a resumable git clone
(or git pull) for many other repositories elsewhere, with a somewhat
lower pull-to-push ratio than kernel.org. Supporting resumption based
on objects, without the repository needing to generate and keep around a
bundle, seems preferable for such repositories.
