The renaming of options define the original value for the new attribute path. This works well if there is only *one* target, but if there are more, we end up recursing into the attribute set of the option definition itself. We now check for that within the parent recursion node (we can't check that from the subnode, because we lack that information about whether it's defined multiple times) and if the subnode consist entirely of a list of definitions, we use mkMerge on it.
