In GAAP days, you weren't crossing a runway as it wasn't active at all times, it was just a piece of taxiway. If you were taxiing for 31 you just zoomed straight over 35 without giving it another thought, no clearance required other than to advise you were on ground frequency by mentioning your call sign.
It's a lot of added complexity, particularly when 17/35 is not in use.
Judging by the number of pilots that weren't getting their radio work right, it's either overly complex, poorly taught or they were all visiting.
