There is also Junio's work on Bundle v3 that was unfortunately

http://public-inbox.org/git/xmqq4m0cry60.fsf@gitster.mtv.corp.google.com/

and previous "What's cooking in git.git" emails.

I am also working on adding external object database support using
previous work by Peff:

http://public-inbox.org/git/20161130210420.15982-1-chriscool@tuxfamily.org/

that could be extended to support clone bundles.
