I am all for removing it but...
Disabling it by default is the first mandatory step, [done] in PHP
5.3, magic_quotes_gpc has been turned off by default at the same time
as providing a -development and -production version of the php.ini
file.

However, such a change might be risky in the PHP5 series!
Release the exact same thing as PHP 5.4 or PHP 6, there is a big
difference in the user perception.
* Is my PHP 5.x application compatible with PHP 6?
* Chance is higher that they will take more care reading a PHP 5.3 ->
PHP 6 Migration guide than a 5.3 -> 5.4.

+1 to remove it in PHP > 5
