As an avid KID player there are things in the salt that true hard-core KID players dont' like.
-We don't to play like to play d5 (gruenfeld) white fianchettoing
-We like closed positions with a king ide attack and super agressive decisive play
Things we don't like:
-Positional(ness) like when white fianchetto's his king bishop
-The Saemisch (f3) combined with the bishop queen battery it's reminiscent of the Austrian 150 attack.
Black in many lines has no spae, a locked center, a kingside attack and dark square control. White gets lots and lots of space. White also has the chance when e5 is played to open the center and get a dynamic equal game but psychologically KID guys want a tactical melee so playing slowly with the fianchetto is a good choice because KID players will sometimes force an attack out of frustration which is good for white beccause the attacks not only not work but can cost blck the game.
black rarely gets a kingside attack. Doing it in the petrosian variation is unsound. Doing it in the averbakh is just dumb and impossible. Doing it in the saemisch is possible but black does it for different reasons and still has to find counterplay on the queenside
In the Mar del Plata where black plays e5 and then Nc6 against the Orthodox setup, black plays very aggressively, advancing all pawns on the kingside. It can be quite sharp. Some consider it thematic of the entire KID. Black may be willing to give up the rook on a8 to gain time.
