In reply to Ramjid Pakishna.

A lot of people complained about that particular feature. Because it does not work in some situations, where you have unusual server configurations, or poorly made plugins, or excessive "security" rules in place. In all those cases, it just doesn't allow code changes to be made, and people got furious about that.

This is the case with pretty much all new features. It won't work for some people, and they get super vocal about the perceived loss of functionality.
