Let me put it all together. You had ECAM fuel pump 1+2 fail. You opened the cross feed to feed the engines from active fuel pump side. ECAM actions complete. Now are you supposed to sit there and watch fuel imbalance develop? Or start a non standard balancing procedure? No. You take a situational assessment decision. Facts of the case? fuel imbalance is developing and there is no procedure to address that if we need that fuel. Options? we can descend to FL300 and use gravity feed on the failed side and stop the imbalance. Risks? Fuel flow at FL300 is 8kg/H/ENG higher which is within our FOB.(This scenario is given by the poster). In any other situation the decision to divert has to come before the need for non standard procedures. The fuel imbalance procedure you yourself quoted by lowering the wing is for OEI. Fuel system may be sensitive or not I don't care to find out, we are not paid for that we just land and give the job of explaining what to do in that case to airbus.The limitation I quoted is in the context of if you happen to have fuel leak one side and loose all fuel on that side and engine not a big deal landing the plane.
