just increases both your workload and the chances you'll inadvertently go IMC.

Best not to go over unless you're sure you can see the other side - you're visual nav only and flying over a waypoint whilst on top would not be a good move.
If you're really not sure, just get down below 3000' or 1000' AGL and make sure your wingtip misses.....
