At least until the Jailbreak tweak is released with patches out this feature, allowing people to retain everything they want. I don't disagree that it works for the average user, but I do agree with the sentiment that it is a false sense of security. Unless maybe you cryptographically verify the deletion (is that possible?) and notify the other party of the successful deletion. But even then a copy could be made beforehand, on-device or with an external camera... I think it's much better to maintain zero expectation of message destruction with all end users.
