Probably because nobody has a very fast Class C breach. I saw a few robots try in quals at North Bay, but they're typically slow and finicky, and the floppiness of the drawbridge makes it harder. The most reliable way to go through the drawbridge and sally port is to have it opened for you from behind.

I think in elims people realize that the time spent for two or three robots to coordinate a Class C defense crossing, is better spent having those robots line up an extra few goals instead. There are generally enough low bar robots that the breach can always be obtained even while ignoring the Class C defenses.
