:::Semantically a slash and a bracket do exactly the same thing. A subpage is not only one containing a slash in the title, a subpage is any page that creates a rigid hierarchy of articles. Your brackets cause exactly the same problem I have with the slashes. As I said putting television in the main title while relegating country to a note ignores that the country/television formation is just as valid. 1976 in Canada (television) is just as valid a heading for this content as 1976 in television (Canada). Using your title makes it seem as though the page could only ever be considered a subdivision of 1976 in television ignoring that it will also be a subdivision of 1976 in Canada.  

 :::Also please review WP:CSD. That you consider redirects to be "incongruous and useless" is not a speedy deletion criteria. RfD is not a complicated process and it is really unacceptable for someone who has been an admin for close to a year to be deleting pages without following procedure. -
