Especially for servers "include list" is very actual. The same for GUI search - items, not listed in the list, could be skipped silently during the search. Hand-typed link to any file not listed could be blocked also.
Individual lists for GUI and server will do the job in a perfect way
The first item the in exclude list determines if the list is a black list or a white list.
If the first item type is an include then the list is a white list (include only).
If the first item type is an exclude then the list is a black list (include everything, except...).
