I think the people who are thinking "ignorantly" are actually thinking realistically. They are thinking of how this could possibly be useful in context in battles(which should have a clear distinction that it may or may not be useful indifferent modes, which people seem to be forgetting). Thinking realistically, "splat dashing" is simply just pressing ZR and ZL in a simple and extraordinarily easy rhythm, so I would never even THINK about it being considered "advanced", let alone a "tech". Those that are saying that there is a use for it(besides speedrunning) are just in their own little dream thinking that "splat dashing" is either going to be applied similarly to techs in smash bros(a fighting game), or are hoping that the ability to perform this "advanced technique" will differentiate a competitive player from a casual player(which is definitely false since anyone can become fluent with "splat dashing" within 30 minutes of practice). Also, I don't find it useful whatsoever since it just leaves hardly any painted space for combat(which will often times determine the winner in little 1v1 battles during matches) which will most likely not be useful in splat zone, tower defense, and definitely not turf war. About speed, You must remember that it is just as difficult to cover neutral area as it is enemy area, as well as the fact that it isn't about who covers the area first, but is about the end result.
