(picking this thread up again because there still hasn't exactly been a 
meeting of minds here)

land polygons have been generated (see 
https://osmdata.openstreetmap.de/data/land-polygons.html ) and 
https://github.com/fossgis/osmdata/issues/7 has been resolved by 
manually "releasing" the coastline.  The current situation in OSM is 
https://overpass-turbo.eu/s/WD8 - at the time of writing this the 
coastline crosses the river north of Buenos Aires.

However, edits are continuing (see 
https://www.openstreetmap.org/changeset/88787419 ).  I'm not convinced 
that moving to one of two extremes, even a small amount at a time, is a 
good idea until there's actually been discussion between the proponents 
of the various positions.

For what it's worth, neither extreme position looks the best answer to 
me - looking at the salinity change between river to ocean at 
https://www.sciencedirect.com/science/article/pii/S0307904X07000716 (see 
https://www.sciencedirect.com/science/article/pii/S0307904X07000716 for 
the key picture) and looking at 
https://de.wikipedia.org/wiki/Datei:Rio_de_la_Plata_BA_2.JPG suggests a 
location some way between the two.  Despite the NASA photo it looks like 
there isn't a "step change" in salinity - and of course values will 
fluctuate based on winds and tides etc.

Best Regards,

Andy
