Right, it's portable, but that's not what 3 was about. It's about being required for first-class access to a desirable platform. It's why Objective-C gained strong, renewed interest when iPhone apps in that language were announced. It's why anyone cares about Javascript. It's why Kotlin adoption grew very fast when Google announced support for it on Android, or why Swift went from nothing to fairly high levels of use practically overnight. That kind of thing.
