You don't go through the TTY model, but read directly from devices (if the kernel allows it). But people will hate you for it, since it doesn't fit with the abstraction layers that are commonly used, one of which is that only characters matter, not keypresses. Consider how such a TUI that directly interacts with keyboard devices (because it wants to detect keyup events) would work over SSH. It cannot. Abstraction layers limit certain functionality, but they also allow workflows to exist that otherwise could not (or would be much more complicated). You have to judge in every instance whether the correct balance has been made, but I don't think this aspect of the Unix terminal design is awful.
