At some point in the future, CFLs and LED bulbs will get cheap enough that it will make sense to replace that bulb whether it has burned out or not. If you look at the unfortunately long discussion I posted on the question, you'll see that it's pretty easy to decide when to do it.
I look forward to your predicted improvements in lighting tech. But in the mean time, I'll upgrade stuff that'll make a bigger difference.
