Question: testing for non-unique id values SC 4.1.1

While checking for non-unique ids validators consider id values of elements that are hidden and not rendered on the page. 
For accessibility,  this is important only when ARIA attributes refer to a hidden element, no?
Otherwise, if the element is  not rendered it does not impact anyone. 
True it may in some cases pose functionality issues if the developer has unwittingly repeated id values and this should be fixed from a code quality / functionality perspective. 
So id values repeated in hidden content that are not referenced by any ARIA attribute do not need to be fixed strictly from an accessibility standpoint. Is this view accurate? 
Thanks,
