No. This is what I had in mind:

git clone --branch=master --depth=2 git.git # get branch master with depth 2
git fetch --depth=10 origin next            # get branch next with depth 10
                                            # master's depth remains 2
git fetch origin                # get (new) branch 'pu' with default depth 2

But your case is interesting. We could specify --depth=v1.8.0.. or
even --depth=v1.8.0~200.. (200 commits before v1.8.0). Somebody may
even go crazy and make --depth=v1.6.0..v1.8.0 work. --depth is
probably not the right name anymore. Any SHA-1 would be allowed as
anchor. But I think we need to wait for reachability bitmap feature to
come first so that we can quickly verify the anchor is reachable from
the public refs.
