Most objectors here are blithely ignoring the school's statement, “From our very foundation in 1904 and for decades afterwards, the senior student was called ‘Head of the School’, so in making the change, we are confirming, not denying, our ethos and traditions.”
It's a return to tradition therefore, so the frantic anti-change frothing smothering this thread is misguided. But hey, why should I spoil their obvious enjoyment of such self-indulgence by introducing facts.
