This came up because of a concern that the slash in [[en:Good cop/bad cop]] would cause a problem. There seems to be no problem there, since there is no "Talk:Good cop" that would serve as a base page for [[en:Talk:Good cop/bad cop]]. However, there IS a [[en:Talk:AC]], which means that [[en:Talk:AC/DC]], which should be a base page, is treated by the software as a subpage of [[en:Talk:AC]]. This means that if someone moves the article [[en:AC]], and ticks the option "move all subpages of talk page, if applicable", then [[en:Talk:AC/DC]] and its subpages will end up separated from the [[en:AC/DC]] article. While I think [[en:AC]] and its talk page are unlikely to be moved, this could be a problem elsewhere.
Subpages are enabled in ns1 (Talk:) on enwiki, and subpages are delimited with a slash "/". Ergo, the fact that [[Talk:AC/DC]] is a subpage of [[Talk:AC]] is expected behaviour. Of course *semantically* [[Talk:AC/DC]] is different to [[Talk:AC/Archive 1]], how is the software supposed to know that? Either subpages are enabled for a namespace, or they're not; trying to say that **most but not all** elegible pages are subpages, is a route to madness. I'm going to recommend WONTFIX on that basis.
WONTFIX because there isn't really a sensible fix. Suck it up.
