Kinda, maybe. Making realistic shorelines by yourself is very hard. Some people use the usual "inaccuracies" of medieval maps to hide the fact they dont know how to. But if you actually care about accuracy, i guess there's no harm in assistance.
I like designing my own world in a very rough sketch and then using generators 100 times an hour to find landmasses that look like what I already designed.
