NIH
I think the "NIH" mindset might only have been at Boeing and not America-wide, as our DC-9 fleet had them.
They were so effective that my employer installed them on the glareshield of the 767 and then the A320, 330, 340.
I think the reason this type of checklist was not used on the DC-8, B747 or L-1011 was the presence of the Second Officer who ran a somewhat-similar mechanical checklist( with sliding windows instead of vertically-flipping) from his position.
And they're not on the 777 due to the electronic checklist.
