Yeah, in the previous commit implementing --print-filtered, we check that all the objects that should be printed to stdout are indeed printed. So later when git repack --filter=... is implemented by using git pack-objects --print-filtered and piping the printed objects to a regular git pack-objects command, I don't think it's necessary to test a lot of objects, as hopefully both pack-objects command are supposed to work well at that point.
