Just not true. The settings are still there and were in the iOS6 betas as well. I know because I would have been affected. Even if the settings were gone from the UI it would still be possible to set them with profiles, which can be distributed via the operators website. Some "advanced" settings that could only be set with profiles have even moved into the UI in later versions of iOS, like Cisco VPN, S/MIME.
