This is not a bug. Arrays are supported for almost all types in Postgres.
It is a generic feature. Just json can hold arrays too, and from PostgreSQL
14 Postgres allows to use similar interface.

If jsonb arrays are faster than Postgres arrays? It depends on the task and
environment. The update of a jsonb array can have the same speed as an
update of a generic array in SQL, but generic arrays have special support
in PL/pgSQL, and there can be significant differences in performance.
