Well the way I see it, in the KID a common plan is to break by playing f5, sometimes transpositioning in the Dutch. In some lines in the Dutch ( I think it was classical) its very strong to be able to push your e and f pawns. The bishop looks weak but soon is released after f5 pawn break, that's the idea.
Also the knight on b4? KID often goes for a strong kingside attack and often the queen knight is being transported to the kingside, as we can see in the e5 line you showed where a knight is on e7, ready to jump out or preparation for f5 pawn break.
In the KID most often you either push e5 or c5 after quickly developing your kingside pieces. The question I have involves the Bg7's quality.
This is a game where e5 was pushed. Now let's check a game with c5 pushed.
