Changing that will break a zillion scripts. That said: If this does need to ever change, then 6.0 is the right time to do it, with register_globals going away. You *could* consider yet another php.ini setting, with all the baggage and issues that brings, to provide a transition from 5.x to 6.x to 7.x Something like: 5.x (as-is, no matter how big .x version goes) 6.x default php.ini to BC ' foo.x ' => 'foo_x' as keys with php.ini setting to make ' foo.x ' => ' foo.x ' for those that want to migrate early 7.x default php.ini is ' foo.x ' => ' foo.x ' with flag to keep old behaviour for the late-adopters 8.x ' foo.x ' => ' foo.x ' is your only option E_DEPRECATED would be issued in 6.x and 7.x if the setting was BC "on" I believe that any time-scale less than that, for the number of scripts that needs to change with INPUT IMAGE, would be a nightmare for users, imho. -- Some people have a "gift" link here.
