Hi,
Disclaimer: I have nothing to do with the SeaMap, I'm just a coast dweller.

I do not see, that the seamark:xxx=cemetery will replace the
landuse=cemetery, so I do not see a fearable change there.
I see that there is a notable difference for navigating purposes
possible - not every cemetery on the sea is automagically a seamark:xxx
- but I may be corrected here.

Please keep on the spur - no one talks about such main differences - but
you cannot tag two different impacts with just one simple tag.

Living in Karlsruhe this is said easily - no pun intended - but living
at the coast I know of the differences even I am no 'seaman'.
Yes, I consider some landmarks only visible on land and some
seamark:landmark only visible by sea.
The problem is, to distinguish those at the 'border strip'.

Now I think you draw a 'Black man' (bogeyman) on a black wall ...

Well, 'routable maps' and 'navigation charts' are for quite the same
purpose - but each need there own special tags sometimes, may be even on
the same object.
I do not see that some(!) additional data on a border strip is really a
problem here.
