Comment (by dd32):

 I have no objections, to either the main file just including everything
 else, or using a autoloader (probably in the future - Sorry there wasn't a
 common prefix!)

 The only potential issue would be an incomplete failed update which then
 couldn't be completed from within wp-admin. As it is, the chances of a
 failed *major* update leaving WordPress in a state that WordPress can
 update itself again is rather slim.
