Copper bulbs are fine

I'm just posting this because so many people are whining about the copper bulb change.

Blocks should be consistent. It makes it easier to remember things and plan things.

Yes, a ton of guys are whining. But just saying, there is also a (rather silent) bunch of people who prefer things consistent. Powercreep in redstone blocks would lead to a weird situation where people make nonsensical contraptions just because new blocks are better. Contraptions should be "readable" - we should be able to figure out what they do by looking at one closely. That gets more difficult if many blocks have some random redstone trait.
