Relations (tables) have always had both pg_class and pg_type entries.
The pg_class entry denotes the relation proper, the pg_type entry
denotes the relation's rowtype.

Composite types have the same two entries, there's just a different
notion of which one is primary.

(The reason a composite type has to have a pg_class entry is that
it has pg_attribute entries, and those have to have something in
pg_class for their attrelid to link to.)
