Are you sure nothing else changed, just this transformation you mentioned?
https://github.com/JetBrains/kotlin/blob/1.2.0/libraries/stdlib/src/generated/_Collections.kt#L615

public inline fun <T> Iterable<T>.filter(predicate: (T) -> Boolean): List<T> {
    return filterTo(ArrayList<T>(), predicate)
}

https://github.com/JetBrains/kotlin/blob/1.2.0/libraries/stdlib/src/generated/_Collections.kt#L688

public inline fun <T, C : MutableCollection<in T>> Iterable<T>.filterTo(destination: C, predicate: (T) -> Boolean): C {
    for (element in this) if (predicate(element)) destination.add(element)
    return destination
}

To me seems nearly the same to what you've done with several minor differences.
