HOW DARE YOU CHALLENGE THE POWER OF THE UNDERSCORE??!!?!

Looking out a few months I don't think it's unreasonable for us to come up with a lightweight ajax API, either as a proper subset of what we have or something else entirely. 

We're talking about making scripts not be executed by default but there will still need to be some way to execute them so that older code can work. And we need some way that a custom build can override or stub out the functionality. We've discussed several approaches. If we're out of other options then it's just a case of choosing.
