Boac, I don't see any problem with having enough fuel to shoot at least 2 approaches at destination, then divert, hold, then land with A safe minimum. The extra approach can be used for multiple events, not only a missed approach. Fuel = thinking time, especially when things don't go to plan.
I have had to carry out 2 precautionary shutdowns due to engine anti ice problems and an alternate gear extension before.These times, the extra approach fuel was useful to fully brief the crew and go through the drills slow time.
Do the major civvie carriers track individual fleet fuel discrepancy? Our best to worst accounts for 5% of cruise fuel.
