IMO, shutter speeds above 1/60 second for sheet film and larger format tool film is not an issue. The slower speeds below one second is more important.
If there is too much light to achieve the needed film exposure, add neutral density filter., which has also been as rare as needing shutter speeds of 1/120 second or higher.

For 35mm or Digital, 1/4000 or 1/8000 at times is not fast enough.

Some photographers need higher shutter speeds to ratio ambient to flash or hot light to control how bright or dark the background is in relation to the foreground lighting. For example, portrait and event photography, architecture interiors, macro shooting. Or just to control motion in landscapes, water falls, tree movement in wind, etc.
