Fire hazard from fuses is only one reason not to use them.
A BIG reason not to use fuses is that once lit, there is no "abort". If you have electrical ignition, you count down and if something goes wrong you simply stop and do not hit the launch button. This could be the pad tipping over, an aircraft suddenly entering the airspace or a person not connected to or aware of the launch suddenly entering the area on foot, bicycle or whatever.
