No. One of the reasons is that the sync does not propagate down. Devices with own caches have no way to get this information and use it to flush their caches.
Additionally you don't always want all and everything flushed. Some pieces of data always need to be on disk, others can be written delayed or even out of order. Those are patterns that you can't implement without RAW devices.
