This is not a "feature." It is a feature.

. You need crossing runways for different wind conditions. This is done based on % of time a wind blows in a certain direction. For LAX, it's either east or west, so 4 || runways do the job. However the runways are too close to be used together and that's why the south runway (25L) is being moved a bit south, so a taxiway can go in-between the two runways to allow for simultaneous ops. There have been a number of nasty runway incursions, with planes taking off and landing.
As for SFO, we need the intersecting runways for varying wind conditions. Same goes for Chicago. Chicago is notorious for bad weather and wind can come pretty much from any direction. If the crosswind is too strong, a particular runway can't be used. That's basically it.

Trust me, it's just you. All the seats in Y are the same. Maybe some have tables in the armrest, and maybe some are missing an arm rest near the window, but they're all pretty much the same dimension-wise.
