Not really, as he writes on his web page, his tools tries to repair the
coastlines. And as I use them, too, I know that this automatic "repair"
can break the result even more. I have added some additional 
post-precessing checks and patched osmcoastline to bail out on more
errors to make sure that the result is for me really useable.

Currently the coastlines are so heavy broken, that osmcoastline only
seg.faults. So there will be no update with the broken costlines.
I assume that why geofabrik does not report coastlines errors anymore,
