it's just not enabled on larger sites such as the English Wikipedia. It's being tracked by bug https://bugzilla.wikimedia.org/show_bug.cgi?id=5220.
This is definitely needed. (I remember the debates about implementing this at all when it was first under development; I am quite glad that it exists.)

"enotifusertalkpages" as being enabled). This default behavior is generally helpful on small wikis where adjusting your preferences isn't a top priority (such as strategy.wikimedia.org or meta.wikimedia.org). For established users on a larger project, you'd probably want to change the default to avoid startling people.
The grandfathered default for current users may be different from the default for new users. The default for new users could still be to receive alerts.
It should be clearer how and where to set/unset this preference, however -- it really is central to how people use the Projects.
