I'm not clear on what that actually means.
It almost sounds like you're saying that we'll be able to text from our Apple devices to non-Apple devices without benefit of the telephone network, but I'm pretty sure that's just wishful thinking.
SMS/MMS traffic still has to go into the telephone system to reach its intended recipient. There is no practical way around that.
"How about "Are you sure you want to send this?" Then we can rethink it or give us a choice of how long we want to think about it. Oh well.
But that would add one or more extra steps to sending every message, and I, and perhaps most people, would find that unacceptable.
