That would be perfect. But if it´s too difficult to implement, I could
imagine a simple semi-automatic approach:

Implement a mkgmap option "--seapoint-file=somefile.txt". In "somefile.txt"
the user can put a list of coordinates (points) that are somewhere in the
sea areas. If mkgmap processes a tile without coastline and there is a point
from the list inside the tile, make it sea, otherwise land. So the user can
"repair" seaholes easily by just adding one point within this area to the
text file. People may share their seapoint lists. After some time there will
be so many seapoints in the lists that holes in the sea will become
extremely unlikely.
