I'd be happy to disable this feature for now (and another undocumented feature I won't mention :-)

Oh come on :-)

but my first inclination is to leave it in and simply not document or encourage it. That way, the only folks likely to use it are those who go out of their way to look for it because they really need it. And I /do/ think there are at least a few cases where its use is entirely appropriate.

Which ones do you think of? Maybe links to nearly static pages, like [[NPOV]]. But I think we don't have many articles of this kind, so maybe we can handle this like we do now, by pointing the reader explicitely to the heading.

The problem is that most people learn the wiki syntax by reading the source code. (I just browsed the NPOV page and learned how to link to meta :-) So sooner or later it will get used :-(
