You aren`t REALLY ensuring compatability of an entire script, just the $_SERVER (etc) arrays.
There is still one LARGE difference however. $_SERVER, $_POST, etc are all superglobal arrays, which means you don`t have to do things like:
function foo()
{
global $_SERVER;
}
In your example, the user would still have to have a global ... statement in any user functions they declared.
Your example solves a LOT of problems, but not all :)
