Selecting epub from that list currently means "use original_epub if it is present otherwise use epub".
If I were to add original_epub to the list, then the meaning of selecting epub must be changed to "use epub even if original_epub is present".
Then there will be inconsistent behaviors between the single and bulk convert dialogs, since a bulk conversion will always use original_epub in preference to epub. And that will create confusion of the sort: "I get different results running this conversion from epub in bulk and single mode". Or it will require yet another option in the bulk conversion dialog to tell it to not use originals.
Generally speaking, adding an extra option, increases the degrees of freedom, thereby increasing complexity and confusion. Ordinarily, I would not mind doing that, but in this case its benefit does not outweigh its harm.
Either:
1) You do not edit the output of conversion in external tools
In this case original_epub is harmless to you
2) You edit the output of the conversion in external tools
You simply need to train yourself to delete original_epub once you're done editing. Training yourself to do that is a lot easier than training yourself to maintain a backup of the original before converting in case the conversion messes up.
Step back for a moment and imagine that you hadn't used calibre before this feature was introduced, then this would be what you would do without really thinking about it.
3) You never feel the need to rerun a conversion on an original/you maintain originals outside calibre
In this case simply disable the feature, and you will never see an original_epub
