That is very true. However, there are many benefits to these being in the game. For example, all of these mechanisms/circuits would become much more compact. Also, some of the normal versions of these things have lag or create noise, which is annoying. Also, how would you create a repeater without a delay?
Have you guys ever heard of project red (redpower)? It has some really compact logic blocks that are exactly wha you described. You could even place them on walls to have it more compact, or use these wires to have a signal travelling long distances without losing strength (and without delay).
I have used redpower and project red, and neither of them add the things on this list, other than toggle latch and pulse former gates. Neither of those add things like pistons that move pressure plates (frames sort of do that, but they are designed for larger scale jobs, and are bulky compared to a sticky piston) or a repeater that adds no delay, or any of the other things in the original post.
Actually you do still need repeaters, red alloy wire does need a repeater after 255 blocks, not to mention that red alloy wire is really laggy compared to vanilla redstone. As for funky locomotion, it is more bulky than a sticky piston to move 1 block, because with funky locomotion you need 2 frame motors to move a block back and forth, while you can use just 1 sticky piston. (Not to mention RF usage).
