Where is "Mission Control" on an iPhone or iPad? Do you mean the app switcher? Swipe up on Home screen opens app switcher/multi-tasking, which does allow a force-quit of apps (with an additional gesture) as well as simply switching between running apps.
However, there are two, different purposes for Mission Control on Mac: manage a multi-desktop/multi-display environment, and locate/bring to top a window that may be hidden behind other windows. That second part of Mission Control's mission is similar to app switcher. However, the gesture used to move a window to an alternate desktop/display is a click-and-drag-up, very similar to the swipe-up used in iOS app switcher for force-quitting an app.
There's not a way to quit an app from Mission Control - a right-click/CTRL-click on a window does not open a menu. There are no control boxes/buttons in the corners of the windows for close/minimize/full-screen. So when it comes to human interface design, the functionality you seek would have to be implemented in ways accessible to mouse and keyboard-only users as well as providing the trackpad gesture you desire.
I can see the argument for adding quit-app functionality to Mission Control, but there's also an argument for sticking to its traditional functionality.
