I don't like it either.
I think allowing pg_dump to dump the data in an unlogged table is not
only reasonable, but essential. Imagine that someone determines that
his reliability needs will be adequately served by unlogged tables plus
hourly backups. Now you're going to tell him that that doesn't work
because pg_dump arbitrarily excludes the data in unlogged tables?
