No new object type.  Why should it?  But it has to have a config variable 
which says what type of packs/loose objects it has (and you will not be 
able to mix them).

However, pack v4 had more goodies than just being faster; it also promised 
to have smaller packs.  And pack v4 would need to have the same 
infrastructure of repacking if the client does not understand v4 packs.
