Those things might make sense if one building is on fire, but the scale of these fires and similarly sized forest fires make targeting individual building useless - there are hundreds or thousands of buildings on fire.
Forest fire fighting is pretty contentious, but we now have very specialized planes and helicopters that I assume didn’t exist decades ago. Similarly there are 747s that drop 20k gallons of fire retardant that I assume is new tech. Not sure if trenches are new or not, but also pretty common for forest fires.
