Actually DC did addressed when the Earth-One Batman and Robin, Green Arrow , Vigilante all first appeared. It dropped the ball on everybody else in your list using the very same first appearance for both the Earth-One and Earth-Two versions.

What DC didn't address was any continuity hiccups that selecting those issues produced.
