It definitely helps with getting out of defense to drop one set of omnis. Instantly breaks a T-bone pin allowing the defended robot to spin around and pass the other robot. You're right in that this trick only really works if the omnis and traction wheels spin around the same speed, but it's a neat feature.
The other thing to consider about drop height is that once one set of traction wheels *completely* leaves the ground, extra drop is "wasted" as your base's support polygon is already entirely contained in the other 4 wheels. I think once you get past 3/16" drop you're in that territory.
