What does concern me, and was the first thought in my mind upon reading the opening post, is that Cold Weather ops require leaving the wing clean until just prior to takeoff, to avoid possible ice accretion in the various flap assemblies during taxy.

With "Flaps" now being a part of the 'After Start' checklist on our (B777) ECL, it concerns me that the potential exists, with winter coming, to miss them on the 'Before Takeoff' checklist if the item has been overriden on the 'After Start' checklist. Yup, I know that the checklist should be held until all open items are completed, but one more hole in the Swiss cheese..........

I was under the impression the 777 had 2 levels of protection against that:

1. Closed loop items on the electronic checklist are colour coded so it's easy o spot an incomplete item.

2. TO config warning when advancing power.

Am I mistaken?
