Yes, read the CREATE ROLE documentation:
CREATEUSER
NOCREATEUSER
These clauses are an obsolete, but still accepted, spelling of
SUPERUSER and NOSUPERUSER. Note that they are not equivalent to
CREATEROLE as one might naively expect!

The proposed patch breaks backward compatibility, which is the only
reason we still allow these keywords at all.
