If you don't want it you still can revert it. You can add there file under /etc/sudoers.d e.g. /etc/sudoers.d/secure_path_revert.
With this approach you can still use default sudoers and have it updated after each update of sudo and also have your own configuration under /etc/sudoers.d directory.
$ cat /etc/sudoers.d/secure_path_revert
