In combat jump uses bonus action, so that's something player needs to opt into. Also in early iterations, jump and disengage were one and the same.
I do agree that jump feels really tedious to use during exploration - from from having to click, lound "thump", control being taken away from the player as characters finish their skill animations, companions not quite managing to follow you without stepping into surfaces.
I think it would be nicer if during exploration, it were taken into account when pathfinding - automatically jumping over hazards, and when necessary.
