>> Both USB and U1 have short circuit protected outputs. You mean, power rails on USB connectors at a computer are short-circuit protected? This is true, but the protection is often a non-resettable SMD fuse somewhere in the middle of a very big PCB called mainboard... I'd prefer not to blow that one.
>The trouble with polarity protection (this is what we're talking about isn't >?) is the drop voltage involved with diode. Only if you're using a diode in series. You could also use the fuse and a reasonably strong schottky diode from ground. So, reverse polarity will not go beyond 0.5V, and the fuse will blow when strong reverse power is applied.
