I think there is also a lot of 'boxed in thinking'. That is to say if you have a f2.8 lens then you need to stop down to f5.6 to get best results and likewise if you have an f4 lens then it will need to be f8 to get most out of it.
Get over it. Yes old lenses may behave like this but not necessarily the truth with newer lenses.
Of course this is complete BS.
The Nikon 400mm f2.8 AFS is as optically good at f2.8 as at f8. There is almost no difference between any of the stops between f2.8 - f8.
But there is more than double the dof between f2.8 and f8 and shooting moving birds at 30-40 feet you need all the lattitiude you can get. That's why many people use f8 or smaller. Anyway...the Fuji 100-400 and teleconverter prevent me from using anything wider.
