Using is a bad standard. It doesn't do the obvious thing (that is following foreign keys), it requires a heavy amount of bad conventions, it fails for the not too rare case where you need more than one FK between the same two tables, and if you go strictly with the standard (good for Postgres that it doesn't), it breaks the table-aware semantics of column names.

Meanwhile, the obvious natural way to make joins isn't available.
