I have no idea how widely used that option is. > Another question that's been touched upon but not explicitly discussed, is > whether we should change the default to "scram-sha-256".

I think that we should investigate how many connectors have support for SCRAM or are likely to do so by the time v10 is released. A *lot* of people are using connectors that are not based on libpq, especially JDBC but I think many of the others as well. If most of those are going to support SCRAM by the time v10 comes out, cool, but if not, maybe it's wise to hold off for a release before flipping the default.
