Seeing each other in N4

Oh, okay. Usually most of those are first-timers for me and then you just know it's possible and opponent can pull it off. Nobody pulled the Super Jump 6" into the air + BS Attack against me back in N3 and afaik it's still possible, but nerfed. Also you can't shoot back arc just as you could back in N3 according to rules I mentioned above. So these would be prevalent as long as someone read about those online/figured out themselves and brought it to games until people populate it among each other in local meta. Didn't happen to me, and never desired to learn to use this trick myself.
But, I see your point, and I agree in a way you talk about all this your, point of view and approach seem to be reasonable. For me it's just being aware equals it's possible to encounter and use it during the game.
