This would be great.

If you have the disk space, you might also keep N latest coastline 
extracts, so that when the coastline gets broken somewhere, a 
work-around of using an older extract exists.

I will probably change my workflow so that I will generate the boundary 
data directly from the Geofabrik finland.osm.pbf, but I suppose it could 
be very useful for others. Right now, many boundaries inside Finland are 
either non-existent or broken.
