I noticed the same in parse/print string:

static int parse_string(DeviceState *dev, Property *prop, const char *str)
{
     char **ptr = qdev_get_prop_ptr(dev, prop);

     if (*ptr)
         qemu_free(*ptr);
     *ptr = qemu_strdup(str);
     return 0;
}

static int print_string(DeviceState *dev, Property *prop, char *dest, 
size_t len)
{
     char **ptr = qdev_get_prop_ptr(dev, prop);
     if (!*ptr)
         return snprintf(dest, len, "<null>");
     return snprintf(dest, len, "\"%s\"", *ptr);
}

It looks like printing representation is chosen "for the user", not for 
parsing.
