Comment:

 samo9789 - Thanks for the patch, and sorry for the delay in response.

 In general, I would not recommend the use of the 'list_cats' filter for
 this purpose - if you want to prevent terms from being displayed in, say,
 `wp_list_categories()`, you're much better off passing an 'exclude'
 parameter to that function, or filtering 'get_terms'. That being said, I
 think you're right that there's no good reason to generate an empty
 element.
