Villages could spawn along rivers

In human history, it was common for villages, towns, and even cities to be alongside major sources of water, like rivers or oceans.

Villages in minecraft should work this way, as well. Spawning alongside oceans would not only benefit village generation due to level terrain near the seas or rivers, but also would help players in locating a village, as to only need a boat and a spyglass to locate villages.

This could promote exploration of ones world, and encourage players learn navigation through their world early on, without the pure use of coordinates.
