I read old Mechanics Illustrated and you should have heard the controversy when Detroit integrated the ignition switch with the starter back in the 50s, eliminating the need to engage the starter with the foot pedal. You would have thought the world was coming to an end - The horror to think you would be stranded out there when this new fangled ignition switch failed and you couldn't manually engage the bendix.
Nothing changes does it :)
Although my heart did race a bit when the 2019 Sahara would shut down to save fuel - nothing I would like on the trails, although I know you can bypass that.
