What are the current accepts best practices for determining where to "cut
off" the coastline and to begin a river or bay type feature? The wiki seems
to be in disagreement about this, and I've read chatter about switching to
ocean polygons.

Let's take the mighty Potomac River. It is tidal from the mouth to points
upstream from Washinton, DC, yet at some point it switches to waterway
areas and relations. Would it be appropriate to transition the entire river
to a multipolygon and end the ocean at the mouth? Perhaps the whole
Chesapeake Bay should be upstream from the coastline. Anyone ever try
converting this massive coastline areas? What are the best practices?
