Should Formula One Abandon Fuel Flow Limits?

Mercedes, AGP. (C)

    When Pirelli became Formula One's latest tyre supplier, they were mandated to provide a tyre that degrades quickly, thereby forcing the various teams' strategists to rethink how they attack each race meeting. No longer could the drivers push to the limits and have flexibility in their stategies. Instead they had to nurse the tyres which once they'd reached the precipice of adhesion, would literally fall off the cliff in the space of a lap or two, thus necessitating a pit stop for new boots. Remember Michael Schumacher's qualifying-esque in and out laps around pitstop times to demoralise the opposition during his Ferrari heyday? In recent times the drivers seem cautious on their in and out laps. Recognising they'd possibly gone too far, Pirelli to their credit have produced more durable tyres for the 2015 season. They still degrade quickly, but not to the startling levels of previous seasons. 
    Now to accompany the new turbo powerplants we have fuel flow limits, whereas a maximum amount of fuel of 100kg/hour is allowed to be utilised. We like the idea of the cars carrying a finite amount of fuel in their tanks to cover the entire race distance, once again forcing teams to evaluate their strategies, but why is the amount that the powerplants can draw upon at any given time legislated? We all know more fuel flowing through an engine's veins produces more power, so why not leave the fuel flow rate to the teams to manage? They still only have a certain amount of fuel to get their cars to the chequered flag. Does limiting the fuel flow rate stifle the powerplant's potential? Is qualifying now the only time we see the pinnacle of motorsport at its fastest? 
    Sure is nice to see F1 cars throwing up sparks from their titanium skid blocks though. An intriguing race in China looms. Will Ferrari continue to challenge Mercedes? Ciao....
