A few years ago I was reading some blogs on how to harden your WP site, and one of the things suggested was to rename your install.php file so that someone couldn't re-install a new WP site over top of the current one.
It appears that when you update WP now the install.php file is put back. I've been trying to google whether this step is still necessary, but haven't found anything useful.
Any hard evidence this is still a good thing to implement? Or can I safely take this off my checklist of things to do.
