That's interesting.

Repacking immediately after cloning brings it down to what is expected.

In any case, after this "shallow" stuff, repeated "fetch --depth 99" seems to fetch 0 object and 3400 objects alternately, and the shallow file alternates between 900 bytes and 11000 bytes.
We would need to take a deeper look into what this series does, before moving it to 'next'.
