My opinion on mapping out roughs is that they are often so nebulous that it leads to messy course maps and is better to just leave them out. Most golfers understand that if it isn't within the fairway, it is rough. No need to really draw it out. There are some exceptions that I've seen where the boundaries are very clear and could be easily mapped. But those are few and far between.
