Latest Git does this. If the server is later than 1.4.3.3 then
the receive-pack process can actually store the pack file rather
than unpacking it into loose objects. The downside is that it will
copy any missing base objects onto the end of a thin pack to make
it not-thin.
There's actually a limit that controls when to keep the pack and when
not to (receive.unpackLimit). In 1.4.3.3 this defaulted to 5000
objects, which meant all but the largest pushes will be exploded
into loose objects. In 1.5.0-rc0 that limit changed from 5000 to
100, though Nico did a lot of study and discovered that the optimum
is likely 3. But that tends to create too many pack files so 100
was arbitrarily chosen.
So if the user pushes <100 objects to a 1.5.0-rc0 server we unpack
to loose; >= 100 we keep the pack file. Perhaps this would help
