Make villages mainly spawn near oceans and rivers

The way most real ancient civilizations thrived was by building their towns along rivers and oceans to bring water to their crops. With the new changes to river generation, I think it would be nice if villagers mainly spawned directly adjacent to rivers. This way when transporting villagers they can be moved along the river and that multiple villages could be connected via a river. Maybe there could be a mechanic of fisherman villagers traveling between villages are returning with a different type of fish to sell instead of the usual. For that change, it would require each village to have a set fish for each fisherman to sell which might be annoying for some players so it would require tweaking. I think this change would be good for Minecraft as a whole because it would add a new level of gameplay when searching for villages instead of aimlessly wandering.
