Moot is a little strong and the percentage I think is just a "bit" high.
One stop can be a huge difference when it is needed (for example indoor sports).
Also you could say the same about f/2.8 and f/4! One stop here too! Which would you prefer to use for an inside event, an f/2.8 or the f/4 (pick the FL 24-Xs also 70-200s).
And I would think more than 1 out of 1000 photographers that this is not moot for.
But you are right in some don't need the difference!
