I have used it without problems, however currently all geofabrik 
extracts I had used (even Australia/Oceania or Lower Saxony) worked on 
the old version without problems too, while often these extracts caused 
severe flooding (haven't got any broken extracts saved however)...
Also not really sure if my command line makes sense:
/generate-sea=--generate-sea=extend-sea-sectors,close-gaps=6000,floodblocker,fbgap=50,fbthres=500,fbratio=5/

(until now I have been using: 
/generate-sea=--generate-sea=polygons,extend-sea-sectors,close-gaps=6000/ )

I think it is safe to commit the coast branch to trunk (and maybe 
include some defaults in the help file, especially I have no clue about 
a sensible fbration value), I could not note any problems.....
