Is this list of privileges too generous to a developer?

 Hi,

    CONNECT  <--------------------------------Role
      ALTER SESSION
      CREATE CLUSTER
      CREATE DATABASE LINK
      CREATE SEQUENCE
      CREATE SESSION
      CREATE SYNONYM
      CREATE TABLE
      CREATE VIEW
    CREATE ANY INDEX
    CREATE SNAPSHOT
    CREATE SYNONYM
    RESOURCE  <------------------------------Role
      CREATE CLUSTER
      CREATE INDEXTYPE
      CREATE OPERATOR
      CREATE PROCEDURE
      CREATE SEQUENCE
      CREATE TABLE
      CREATE TRIGGER
      CREATE TYPE
    SELECT ANY DICTIONARY
    SELECT ANY TABLE
    UNLIMITED TABLESPACE

Above is a list of system privileges given to a developer in a production database.   Is this kind of privilege list normally given to a developer?  For some reasons the role CONNECT contains many system privileges.

Thanks,

Simon
