You are right that this proposal is not necessarily about an
unsurfaced way, it could well be covered with asphalt. A "path" like
we see it in OSM is a way that is not suitable for cars (too small),
while this is about roads (width should permit a car to take it).

Yes, this would fit the proposed tag. As you can see from your picture
not beeing aware about the tide situation can cost your life. IMHO
this kind of road merits its own main highway tag, it would be too
dangerous to rely on subtags, and it's overall characteristics are too
different from a "normal road" (a road which doesn't get regularily
flooded).
