JavaScript as an alternative to AppleScript on OS X Yosemite

Given Apple's well-known antipathy to the idea of browser engines other than WebKit and scripting languages other than JavaScript on iOS (yes, yes, I know you can find Python/Lua/Lisp/whatever apps on iOS; I mean as a general rule and for inter-app automation), could this be a prelude to allowing some sort of sandboxed-app automation interface on iOS? That is, allow a JavaScript implementation running on iOS to "drive" apps via this object model?

(Genuine question here. I have no idea whether I'm blowing smoke or whether this is a plausible long-term direction for Apple to take iOS.)

(I expect to have the ability to introspect and manipulate Swift objects in the near future as well, and have a talk on preliminary research of low-level Swift object runtime metadata at #AltConf a couple days ago. The console will also support some of Swift's syntax, such as the named-argument-style method calls.)

JavaScript is just another interface to Apple's "Open Scripting Architecture (OSA)." Previously, AppleScript was the only way to use it. The fact that they added another language indicates nothing about whether OSA will ever come to iOS. My guess is it won't; the new extensions APIs will likely handle any inter-app communication Apple wants to allow, because they are designed with iOS's sandbox model in mind already.

Put another way, Javascript is to AppleScript with respect to OS X automation, as Scala is to Java on the JVM. The existence of Scala does not indicate that the JVM will be ported to the Haiku OS. (There may be a better analogy but that's what I came up with.)

In the general case, for published apps, I'm not seeing it happen. Apple seems to be super focused on sandboxing and separating components on iOS. Even with the new iOS8 extensions, everything needs to be user triggered and even then, extensions live on separate islands.

It's doubtful they'll change that model since it would defeat the "you can't break your idevice even if you tried" feeling for end users and the app store.
