It is true . . . you will not get violated . . . golden, golden rule at ORD is NEVER, EVER stop your aircraft. Keep it moving somewhere, just don't hit anybody or anything.
The best taxi clearance I have ever personally heard on the radio at ORD was for a Polish (LOT) heavy - it went something like this after several radio transmissions where the LOT pilot just could not get the taxi clearance readback correct for the rather complicated taxi instruction to the runway - "LOT 123 Heavy taxi to 32L, I don't care how you get there, just get there, and don't hit anybody or anything." Guess what happened next? Everybody survived!!
ORD is the best. You gotta love one of the worlds busiest airports where if you just keep moving you will not get in trouble, where there is only ONE departure procedure, and it is radar vectored.
