This changesets moves the coastline in a huge area away from the original coast to the wrong place. Looking at the aerial images this looks to me like a marshy area affected by tides and therefore part of the ocean.

See https://osmdata.openstreetmap.de/internal/coastline/ and https://tools.geofabrik.de/osmi/?view=coastline&lon=67.81567&lat=24.12069&zoom=9&overlays=coastline for the affected area.

Please revert this change.
