As far as I know osmcoastline is currently only able to close the 
Antarctica coastline on its own and not other open ends further north.  
So these are currently needed for correct processing.  The Antarctica 
closure segments exist as well (being split into several ways recently 
and thereby complicating things a bit) but they are tagged 
coastline=bogus to allow closing at different limits depending on the 
coordinate system used.

Ideally none of these would be in the database (because as you said 
there is no coastline there).

On the other hand you could of course also argue the same way that 
multipolygons extending across the 180°-Meridian should also be 
possible...
