I think the scale to 0.95 while `pop`ing or `push`ing will leave some blank space and make developers annoying\r\n2. Removing this style can make `<Navigator/>` more native. As you know, customizing the `<NavigatorIOS/>` is not as easy as `<Navigator/>`. Since `<Navigator/>` does not meet the latest Material Design guideline of Android, and preserving this is no use with Android developers.\r\n3. I think removing a transition can improve the performance, even just a little bit.\r\n\r\nIf there still some concern about this in RN development group, I hope at least providing a public API to manually disable this feature.\r\n\r\n___Screenshots and sample code showing the difference listed below___\r\n\r\n#
