You're assuming a receiver who is accepting a zeroconf transaction; most receivers don't.

For instance, when I deposit funds on my exchange they don't credit those funds until 4 confirmations, so I very much cafe about how long it takes to get the first confirmation.

Yes, the receiver can tell the sender up-front that they are only willing accept 4-confirmations, and put that on the sender to figure out, but the sender then only cares because it's the receiver's requirement. The receiver is the one who cares.
