Summary:
I was comparing `<TouchableOpacity>` to `UIButton` in iOS and it just doesn't feel native. The initial delay was fixed by https://github.com/facebook/react-native/pull/10866 but still there is a lag between button release and animation.
I'm also not sure what `_hideTimeout` was used for. When logging `touchableHandle*` events looks like `touchableHandleActivePressIn` is called first, then `touchableHandleActivePressOut` and then `touchableHandlePress`. Which means the fade in animation from `touchableHandleActivePressOut` was interrupted by `touchableHandlePress`.
