You're 100% correct from a technical point of view, however in the field, in real life how many times you manage to get those shutter speeds at low ISO, I already struggle with my 100mm lens.
Let's talk about a 135mm portrait Lens, how many times do you shoot portraits in bright sunlight ??
Shooting in the shade you need easily ISO 400 to have shutter speed at 1/250 that if you lose the lens wide open.
Using flash you are at the limit of x sync already.
So my point is we won't be able to exploit the potential of super sharp Tele lenses, I am sure sharpness wise, if you use handheld any 135mm lens what will define sharpness is not the lens but the quantity of light available.
Stepped down in the lab they get sharper, try it handheld at 1/300s f1.8 vs 1/150s f2.8 and tell me if it will get any sharper ?
