I've only tried this out on Fang, but it's just all around an objective improvement for him. As it turns out, not slowing down constantly really helps the feeling of speed!
The speed cuts have their uses, such as cutting vertical corners closer or stopping yourself short when you would have overshot a jump, but those pale in comparison to just being able to move faster. I think the base game should implement this, as well as de-clunking Gunslinger. Then again, he's already way more fun to play as than people give him credit for - making him on par with the others in terms of power level on top of that might run the risk of turning it into Fang Robo Blast 2! Still, though, my fingers are crossed for the next major update, whenever that happens.
