I think that he is referring to that we already break BC with 5.4 (removing
magic_quotes, register_globals, break/continue
$var, allow_call_time_pass_reference, some deprecated session_ functions,
safe_mode, etc. for a complete list see
http://svn.php.net/viewvc/php/php-src/branches/PHP_5_4/UPGRADING?view=3Dmar=
kup
 )

However I tend to agree with you, that this BC break isn't really worth it,
we can see that there are common apps stumbling across this change, and
albeit the new behavior can be useful for many people, they wouldn't really
mind if we add this as a new variable imo.
