Why was it so necessary to hack a protection against deletion of the Main Page? If the Main Page gets deleted, all that happens (thanks to cascade protection, transclusion of the Main Page on other pages and some javascript) is that people with Javascript enabled see a "temporary technical issues" image in the place of the Main Page, and the edit button is removed. Typically the Main Page gets restored within a minute or two, and the perputrator blocked/desysopped. No harm done, beyond a small number of people hitting the Main Page get told to search for the articles they want directly.
With this ill-thought-through move, the Main Page could not be deleted any more, even for legitimate purposes, and its history was flooded with a hoarde of edits by BetaCommandBot, making perusing its history and constructing diffs very difficult.
