What does mean "OA protocol prevents asset loss"?

I've noticed that CoinSpark says that all excessive assets are automatically sent to the last non-OP_RETURN output as change. I couldn't find anything like that in OpenAssets doc while that chart mentions something like that.

My personal opinion: we don't need that kind of babysitting that makes asset tracking only more complicated. However, I'd like to clarify that.

Asset loss is prevented at the user interface level using the "open asset address format" (as we discussed in #7).

If you try to send colored coins to a regular address, you should receive an error from the wallet/API you are using, preventing you from sending colored coins to a wallet that might misspend them.

We don't use special rules like Coinspark, as like you said, it makes asset tracking much more expensive.
