No. This proposal is not about normal roads that may be open or closed 
depending on the tide. This is about unsurfaced paths which are always 
physically accessible (i.e. never "closed"), but will be flooded at high 
tide; using them without knowing that that they become flooded may cost 
your life.

Because the OSM ecosystem is full of software that goes "ah, 
highway=footway, I'll use that and oh, look, there are some extra tags 
that I don't understand, I'll just ignore them" it would be dangerous to 
tag such a way with a normal "highway" value.
