Can we make more dashes scale with movement speed?

I feel like this should be a feature inherent in all dashes, where your movement speed at the time of cast would determine how fast you'd move while dashing. Generally, this would make dashes easier to react to in the early game, and better at maneuvering in fights late game, and would work with boots ( would give you super-fast dashes when initiating, but slow dashes when trying to leave a fight, buying boots would improve your mobility more comprehensively) but also slows, which would mitigate the speed of someone trying to dash away.

Currently, dashes don't interact at all with slows, which means a gapcloser can just negate most of an opponent's slow if both happen at the same time. Though she's in an alright spot at the moment, can feel annoying to play against as a champion with only soft CC, due to how her perma-dash effectively renders her immune to slows when in the middle of a fight. There are also a few champions who feel really irritating in the laning phase, because their gapcloser gives them a huge edge over anyone without that much mobility: one of the reasons why feels bad to lane against is because her Q + W combo is near-instant and therefore really difficult to dodge, and 's shadow allows him to very quickly poke from a huge distance or avoid a gank. If Leblanc's dash and Zed's shadows started out slower, but scaled with their movement speed, they could perhaps afford to be even faster in the late game, though they'd be less oppressive early on.
