I agree with the majority of voices here - this should be and would be great news and a reason to truly celebrate on one condition:

That Jetpack is rebuilt to remove bloat.

In its current distended state there is no way that I would be running it on any of my sites. I've worked way too hard to optimize them to drop in a 200 tonne plugin to weigh down my server.

I'd wager that the average wordpress user has no idea that jetpack is actually larger than the core wordpress install!
