That's a common misconception which only applies to non-print moves. For the majority of moves which involve pushing molten filament through a small nozzle, the speed is governed by how fast you can accelerate the melt rate and extrude the filament. Even at modest accelerations, there is a lag between the carriage and the extruded filament which results in a pressure build up in the hot end before that translates into more filament being extruded from the nozzle. Pressure advance will help to compensate but only up to a point.
Ultimately print move accelerations are determined by the rate that the filament flowing through a tiny nozzle can be accelerated. So although lowering the mass might in theory allow you to use higher XY acceleration, you won't be able to make us of that acceleration unless the molten filament flow rate can keep up.
In a nutshell, carriage mass is not a limiting factor for print moves, so reducing it will only benefit the acceleration for non-print moves and thus have very little effect on reducing overall print time. Higher carriage acceleration will almost certainly not improve print quality due to the lag between the change in carriage velocity and the velocity of the filament coming out of the nozzle. The lower mass may also make "ringing" worse due to the reduced damping effect.
