No, see the earlier discussion about the difference between "old" and 
"new" objects.

Pack-files can contain old objects that were _previously_ stable, so we 
need to make sure that they are at least as stable as the objects they 
replace. In contrast, new loose objects never replace old data, so they 
can always be re-created by just re-doing the git operation.
