There's a lot more to preserving eMMC than just handling power losses. A lot of what proper SSDs is to do the right wear leveling to make sure that damaged flash blocks don't cause corruption. eMMC is a pretty broad term that can cover something that's just a soldered SD card to something with a full-blown wear leveling controller. That's why you still see a lot of eMMC failures in embedded systems when someone forgets to not log to the persistent storage or similar wear heavy operations.
