It's not as easy to implement as it might sound at first, which
is (partially) why it hasn't been done yet.

The biggest benefit is that this is easier to implement, plus it
allows greater flexibility than simple wildcards in links.  For
example, it would be possible to say arbitrarily complex things 
like "all pages in category ABC that aren't on trail DEF" and
the like.
