Why does Ionic default has-bouncing on ion-content to false?

Question

I haven't been able to find documentation on why Ionic would want to default has-bouncing on ion-content to false.

It is my general understanding that the ionic has taken control of the scroll handling from native (ios and android). So, I am trying to understand the limitations of the has-bounce config option. I.e., what will/could break if I set has-bouncing to true?

While we recommend using the custom Scroll features in Ionic in most cases, sometimes (for performance reasons) only the browser’s native overflow scrolling will suffice, and so we’ve made it easy to toggle between the Ionic scroll implementation and overflow scrolling. http://ionicframework.com/docs/api/directive/ionContent/

Side note: It seems that android has a native method to handle this event? (https://developer.android.com/reference/android/widget/ScrollView.html#setOverScrollMode%28int%29).

Thanks in advance for any insights!

The property has-bouncing adds simply an effect when you scroll at the very top of the view or the bottom (see the image). It is set by default to false in Android and true in iOS because it is an iOS default comportement on native apps and not in Android.
