Yeah, I know that one can catch a water using flat surface on the 
desert, but a desert is not a "water source type" IMO. I've tried to not 
include every possible water form on Earth just becuse it could be used 
as a water source - just like I wouldn't mention railways when talking 
about foot paths, even if it's possible to go along the rail track...

waterway=water_point would be interesting type (amenity=water_point 
marine twin), but currently it has only 238 uses and that's something to 
be shown rather on specialized maps (like OpenSeaMap).

> I wouldn’t show man_made=water_tap because it’s either also drinking water, or there’s not much interest in showing it in this general purpose map. I would consider showing wells, because some of them are significant, and would tend to not include water points in the general map (or only at zoom 20+)

It was mentioned many times that we care about drinking water, however I 
think it's too narrow point of view - washing, watering the garden or 
using for the car engine cooling can be also important, especially in 
the outdoor.
