I don't agree. This is a good general rule, but the general
convention on most maps is that the coast goes on the SEA side of
things like coastal swamps and mangroves. As a rule of thumb, if it
has plants growing though the water, it's land, not sea, even if it
happens to be wet.
Doing this your way looks OK at higher zoom levels, but as the
coastline way is used to make the country shapes for low zoom levels,
these ways are out of place. In most temperate areas, the difference
is so small you can't really tell, but this can be very important in
tropical areas where the mangroves can be many km wide. In these
cases, I've never seen a map that shows the coast on the inner edge,
and trying to do so is just wrong.
The original post referred to *tidal* areas. By definition, these are
completely covered at high water, whereas mangroves are not. A mangrove
would be mapped as a natural=wetland, wetland=mangrove on the dry side
of the coastline.
