It's not quite that simple. The area in question is quite a complex river delta, and it needed quite a bit of manual correction to get the coastline correct. You'd have to: 1) run the coastline script to generate data 2) compare the generated data from (1) to the partial data already in the database 3) delete the unused nodes which have been left over when someone deleted the coastline ways 4) fix the day generated in (1) so it was in the correct direction in all cases 5) upload the new data. It seems a long process to go through when the correct data is somewhere in the database if only it could be extracted.
