Safari parental controls disable delete browsing history iPhone

Hey I am interested in accountability for web browsing on the iPad. There are a handful of apps available that have built in accountability and web history reporting, however they are all limited in usefulness because they are designed with practicality as a secondary concern. Most are unstable and lack useful features included in safari. However if apple allowed for a parental control that prevented the deleting of browsing history then it would be unnecessary to run a separate app with limited functionality. I can see this as a feature that many groups would be interested in. I wonder if apple would consider it? What do you think
