Better compared to what?  Currently, all other water features are at
resolution 18, while natural=coastline is at resolution=12.  Resolution 12
means that all lakes that are mapped as natural=coastline will show up
and seriously slow down the map drawing at wide zoom.  It is just plain
illogical that some water features disappear but others do not.

It could be nice to have presets for resolutions in the style file, so
that you could say 'resolution water' in all map features and define
'water' as 18, for instance.
