How robust/(un)safe is CI

These problems generally only occur when the DEVELOPER is unaware. For instance, using the callback function you could simply call it 'callback__username_check' and then it would use the method '_username_check' which is not publically available. Another option is to simply use PHP and call it private, but then it simply returns an error instead of a 404.

For most uses, CI is as (un)safe as programming PHP from scratch, except it speeds up development a lot.
