The only ability I see the fast lenses provide was actually a disadvantage that happened to become a feature, and that is shallow DoF, allowing for separation of subject from the background.

how is it a disadvantage when you can stop the lens down?

The purpose of designing larger apertures was to get more light in. The shallow DoF is a side effect or a by product of doing so.
