A village being hard to see from a distance makes it harder to find, which can be important when one is trying to find the first village in a world so as to have access to trading. (Starting with a readily available village is a hugh advantage, as it provides crops {wheat, beet, carrot, potato) as well as trade)
Once one has one's first pair of villagers there realyy isn't any need to find another village. (although it can be more convenient than tranporting the perishers).
Also, once on has elytra the comparative difficulty in sighting villagers effectively vanishes.
With that in mind, my point really only applies to the critical first village.
