If OSM takes a "all rivers must be connected through lakes", then data 
consumers have a simple job. If OSM says "some will and some won't", 
then data consumers have to process the data to add intra-lake 
connections. If they have to do it some of the time, why bother 
connecting *any* rivers?

I think I'll change to not connecting rivers, unless it's very obvious, 
and leaving data consumers to connect rivers themselves.
