I'd be happy if it stayed like it is, for backwards compatibility. If
not, then there needs to be some reasonably straightforward way for an
app to work out how PHP has messed up its input so that it can put it
back together (compare get_magic_quotes_gpc()).

In any case, it could be better documented. I see it is documented in
these places:

http://www.php.net/manual/en/language.variables.external.php
http://www.php.net/manual/en/faq.html.php

But not in any of these places:

http://www.php.net/manual/en/reserved.variables.get.php
http://www.php.net/manual/en/reserved.variables.post.php
http://www.php.net/manual/en/reserved.variables.cookies.php
