If the idea is to remove all options for default behavior, we'd be removing
--no-statistics, --with-data, and --with-schema at this point.  Maybe we
could go a step further and even rip out --statistics-only (in favor of
--no-schema --no-data --with-statistics).  In general, I do think the list
of pg_dump options is pretty unwieldy at this point.
