What makes you think roundcube (and dbconfig) doesn't use the default
UNIX socket with that configuration?  Again the ‘localhost’ hostname is
treated specially, see mysql(1).

If you're not convinced try to remove the mysqld socket path (or change
it to something else) to something else and watch Roundcube fail to
connect.  Or set ‘skip-networking’ and see Roundcube, dbconfig, and even
`mysql -h localhost -P 3306` ignore INADDR_LOOPBACK:3306.
