www/php4 Well known security record. End of life was > 15 month ago. All true, but I think there are people using it. Unless I'm confused, one can't just use php5 to run php4 code. Unless the continued presence of php4 is a maintenance headache, I think it should still stay. Looking at the logs, it looks like very little has happened since late 2008.
