Okay, what if you are forced to be closer to the subject than you would like and want long DOF. Such as street photography. You'll be off that 2.8 pretty quickly.
Usually I want the thin depth of field. I shoot a lot of F1.4 in the 50~85mm ranges.
If I wanted a long depth of field, I wouldn't be walking around doing street photography with a 70-200 F2.8L II anyways. For street, I usually want wider angles, so I like 28mm to 40mm, and I like F1.4 to F2.8 there. I only go for long depth of field when doing architecture in the street.
If I were buying the F2.8 telephoto lens, I would be stressing to use it for it's F2.8. Otherwise, if stopping down, you just wasted $1000+ and could have been much happier with the lighter, and nearly as good F4L IS. This is my point. We don't buy an F2.8 lens just to stop down.
If depth of field is a problem and you wanted fast glass, the focal length was your issue.
