I would argue that -j DROP should behave exactly as the packet is dropped in the network, while -j REJECT should signal the failure to the application as soon as possible (which it doesn't seem to do).

It does not only make sense, but also is a highly useful testing technique that we use -j DROP in OUTPUT to emulate network losses and see how the application behaves.
