This is probably due to the increased awareness among mappers that verfiability of the tagging is of fundamental importance. The verifiability page (http://wiki.openstreetmap.org/wiki/Verifiability) has been initially created in 2009. > Also it seems like different people has interpreted the distinction > between river and stream differently.

Probably not - and more importantly there are tons of data from imports with no informed decision on river vs. stream for the individual way at all. This does not mean of course that there is no value in keeping this information in the database, especially if for the future there is a clearly verifiable rule. > Something like crossable=* might be a good idea.

Practically this will be next to impossible to determine except at a measurement station where it would make more sense to tag the node. If someone has an idea for a practically measurable quantity that has a clear relation to the discharge of a river that would be useful to tag of course.
