Just a random thought. This feature doesn't seem useful by now due to the clumsy feel IMO, unless one desperately needs a snapshot of opened apps or to close an app. Particularly, considering the fact that you can only gain access to up to 3 apps in the app switcher without any swiping, taping once and opening from home screen sound a more viable approach - if one may fit all the apps involved in his/her main workflow in the same page. 20+ apps are free to choose from with badge counts keeping you up-to-date, and this saves you a press on the home button too. Hope that there would be an in-built gesture or button in the Control Center to call the app switcher in the future iOS release. For iPhone, of course. P.S. did some late edits for more elaboration. sorry if this causes any confusion.
