Has this edit war stabilised?
Apparently it has been blocking coastline updates across the whole
world for /months /now.

(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
I live near the coast and have done coastline processing, including a
great deal worldwide during the redaction.
Salinity and territorial control have seldom been considerations in
where the break between water mapped as waterway=riverbank and
natural=coastline that I have seen. The break is chosen as a convenient
place for mappers and a common view of where the coast of the ocean is,
not based on scientific salinity criteria. For territorial control, look
at all the inlets along the BC or Norwegian coasts.
