To be honest, I don't see the compelling need for this.

I don't disagree that the functionality is nice, however I quite like 
the verbose versions as they are clearer to understand without knowing 
an API function.

Also, most of the cases that you would use these functions are with 
input from GET args and the like. Most frameworks provides wrappers for 
this with handy ways to get the defaults etc.

So overall, I can't see this becoming a core PHP feature.
