It's pretty off-topic for the thread at this point, but I'd be happy to talk about it in a separate thread or on IRC if you're interested. I'd also be interested to hear your thoughts about it.

I'm certainly all for it, and think that it makes things much more sane, though I don't understand why this wouldn't "propagate the magic" that Adam doesn't want to propagate.
