I would use more like --depth=16 or 32 in my local repositories.

Not at all.  And it is not documented, it seems X-<.

Typically you have a pair of files in .git/objects/pack, e.g.

  .git/objects/pack/pack-2e3e3b332b446278f9ff91c4f497bc6ed2626d00.idx
  .git/objects/pack/pack-2e3e3b332b446278f9ff91c4f497bc6ed2626d00.pack

And you can add another file next to them

  .git/objects/pack/pack-2e3e3b332b446278f9ff91c4f497bc6ed2626d00.keep

to prevent the pack from getting repacked.  I think "git clone" does
this for you after an initial import.
