It has to do with how redstone power travels up and down slopes. Now, I don't know the actual algorithms for how it's done in game, but from what I've seen, it works something like this:
- For going uphill, check to see if there's redstone one block up in any direction. If there is, power it at one less strength.
- For going downhill, check to see if the blocks adjacent in any direction are considered powered (redstone block, redstone torch, or a normal block that has powered redstone on it). If there is, power it at one less strength than the highest.
The only reason diodes work is because of the downhill part - because glowstone, slabs and stairs count as transparent blocks, they aren't considered powered, so the downwards part of the algorithm fails. Though I think that if they're going to implement an upward diode, then the diodes themselves should have their own blocks instead of reusing already existing ones.
Slightly more on topic: I voted for colored lamps and upwards diodes. I think colored lamps that would respond to power levels would be annoying to work with. I haven't really gotten into the whole comparator/analog signal business though, so I can't really speak on their usefulness. I approve of colored redstone on the condition that different colors can interact with each other. And personally, I wouldn't get a whole lot of use out of dual way repeaters, but if they work like I think they would (one block, taking a signal from either side and sending out the other), then I can't see how they would ever shut off.
