I don' see what aesthetics come to do here. A random map is ugly. Very ugly. If you add ugly windmills to a ugly map, the map is still ugly.

Now, if someone dislikes windmills, he can use Adventure Pillars mod which replaces all prisons with nice towers. Myself I will never use the mod "delete prisons", did it only because script was 95% already done for my Pillars mod.

The purpose of the mod is to allow all heroes to be in game. Prisons are the most useless object in Heroes games. The heroes in prisons are 99% bad leveled. No use.
