Maybe I'm just missing some better documentation, but my main problems 
with ext/filter are:

1) Many users don't know it exists, or how to use it.
2) It's pretty verbose and complex for such a simple task as "is this 
thing a valid integer?"

Basically, it's a swiss army knife, but people are looking for a pair of 
scissors.

There's a lot of code out there doing things like this:

if ( is_numeric($_GET['user_id']) ) {
     display_user($_GET['user_id']);
}

This is definitely the wrong function to use (what kind of a user ID is 
'-1.5e-50'?) but it *looks* like the right function, and it has a really 
simple name, so people don't bother looking for anything more complicated...
