If you are certain that magic word was working before, then you should report the change in behavior using this. I would be interested in what they say. However, I am not convinced that it ever worked seeing as the current behavior is as I would have expected. When MediaWiki documentation refers to a "talk page", it is referring to a specific system for having discussions about pages. The talk namespace for the "User" namespace is "User talk", not "Message Wall". It is like how it is "User blog talk" for "User blog", "Talk" for the main namespace, "Category talk" for "Category", "Project talk" for "Project", etc. I assume you can see the pattern.

What you have changed it to should definitely work though.
