This is indeed a nice feature to have, and thanks for details of how
this would be accomplished.

One issue is that when cloning a repository, we do not download many
files - we only download one dynamically generated packfile containing
all the objects we want.

You might be interested in some work I'm doing to offload part of the
packfile response to CDNs:

This means that when cloning/fetching, multiple files could be
downloaded, meaning that a scheme like you suggest would be more
worthwhile. (In fact, I allude to such a scheme in the design document
in patch 5.)
