Ordinarily, I do tag the Thalweg as waterway=river, and then the outline
as waterway=riverbank (or natural=water water=lake, or landuse=reservoir
as appropriate). That appears to be what the Wiki recommends. I do
try to maintain a continuous flow line.

I haven't done a lot of waterway tagging, but I've certainly
done some repair of other people's accidents with the banks of major
rivers, and that's how I've done it. It seems to render appropriately, and
I've heard no complaints.
