Comment from jaffadog
Hi. previously, a way with natural=coastline extended from Punta del Este to Punta Rasa - a 100 mile stretch. Unfortunately, this results in coastline, land polygon, and water polygon artifacts to consider this large body of water extending up to Buenos Aires to be land rather than water. So I haveremoved this artificial way and shifted the coastline back to actual land. I believe this is inline with guidance (https://wiki.openstreetmap.org/wiki/Tag:natural=coastline).

also: there was a note on the ways defining the actual shoreline asking that what i have done not be done. However, this seems contrary to guidance; is inconsistent with most of the reset of the OSM map; and like i said, messes up the land and water polygons, and coastline artifacts.

"This results in coastline, land polygon, and water polygon artifacts to consider this large body of water extending up to Buenos Aires to be land rather than water."
That's not quite correct. What happens is that the coastline is only used once a day to update the ocean polygon shapefiles, which are used to render the ocean on the "standard" map layer of openstreetmap.org, the Openstreetmap-carto style.
But to avoid this problem from occuring in the short term, I suggest this compromise:
1) Extend the coastline up above Buenos Aires
But
2) Do not delete the currently tagged riverbank/natural=water area which represents the estuary of the Rio de la Plata.This way, the Rio de la Plata will still be represented as a river (estuary) in Openstreetmap, and the coastline will be at a more reasonable location.
